CORINE Land Cover program
Opis:
Dotychczas zrealizowano trzy edycje programu CORINE Land Cover. Wynikiem pierwszego programu (CLC-90) było opracowanie bazy danych o pokryciu terenu w 1990 r. Celem kolejnego projektu (CLC-2000) było sporządzenie zaktualizowanej bazy danych o pokryciu terenu w 2000 r. oraz bazy danych o zmianach pokrycia terenu w latach 1990-2000. W ramach ostatniego programu CLC-2006, została opracowana baza danych o pokrycia terenu w 2006 r. oraz baza danych zmian pokrycia terenu w latach 2000-2006. Przyjęta metodyka tworzenia bazy CLC-2006 obejmowała integrację danych CLC-2000 i danych CLC-Change, tylko z uwzględnieniem zmian o powierzchni co najmniej 25 ha oraz włączenie małych poligonów do którejś z otaczających form pokrycia terenu. Przyjęcie takiego założenia metodycznego przy tworzeniu bazy o pokryciu terenu w 2006 r. rodzi pytanie, na ile może ono wpływać na szczegółowość wydzieleń zawartych w tej bazie danych. Do sprawdzenia wpływu, jaki wywiera wybór metody generowania bazy danych CLC-2006 na szczegółowość danych o pokryciu terenu, wybrano Obszar Metropolitalny Warszawy. Zgodnie z przyjętymi założeniami metodycznymi (integracja zmian o powierzchni większej niż 5 ha), połączono bazy danych CLC-2000 i bazy danych CLC-Change. W wyniku przeprowadzonej procedury, wygenerowano nową bazę danych o pokryciu terenu poziomu 3 (CLC-2006A). Kolejnym krokiem analiz, było opracowanie szczegółowego zestawienia statystycznego, obejmującego porównanie baz danych CLC-2006 i CLC-2006A. Przeprowadzone analizy wykazały, że przyjęte odmienne poziomy szczegółowości wyznaczania form pokrycia, dają w konsekwencji różne poziomy uogólnienia treści, zarówno pod względem liczby wydzieleń jak i powierzchni poszczególnych form pokrycia terenu. W bazie CLC-2006A, w porównaniu z bazą danych CLC-2006, zwiększyła się liczba zarejestrowanych poligonów. Ich liczba wzrosła z 4340 do 4495, z czego 135 to wydzielenia, których powierzchnia mieści się w przedziale 5-25 ha, a które nie były uwzględnione w bazie CLC-2006. Nastąpił także wielokierunkowy proces zmian powierzchni poszczególnych wydzieleń. Obserwujemy wzrost powierzchni niektórych form pokrycia terenu: terenów przemysłowych lub handlowych (121), miejsc eksploatacji odkrywkowej (131), budów (133), terenów rolniczych z dużym udziałem roślinności naturalnej (243) oraz lasów w stanie zmian (324). Wyniki analiz wskazują na zasadność reinterpretacji bazy CLC-2006, co może w dużym stopniu przyczynić się do poprawy szczegółowości prowadzonych analiz, zwłaszcza przy ocenie powierzchni form pokrycia terenu oraz w analizach wskaźnikowych, np. przy określaniu wskaźników urbanizacji, lesistości lub antropizacji.
Three editions of CORINE Land Cover have been carried out so far. The first program (CLC-90) resulted in the elaboration of a database of land cover in 1990. The aim of the next project (CLC-2000) was to create an up-to-date database of land cover in the year 2000 and a database of changes in land cover in 1990-2000. Finally, the result of the last CLC-2006 program, was the elaboration of a database of land cover in 2006 and a database of changes in land cover in the years 2000-2006. The adopted methodology of creating CLC - 2006 base comprised integration of data of CLC-2000 and CLC-Change, taking into account only changes in areas of at least 25 hectares and the inclusion of small polygons into one of the surrounding forms of land cover. The adoption of such a methodological assumption in the creation of the 2006 land cover basis breeds the question how it can influence the level of detail of divisions contained in this database. Warsaw Metropolitan Area has been chosen to verify the influence of the choice of method of generating the CLC-2006 data base on the level of detail of land cover data. CLC-2000 and CLC-Change databases were merged according to the adopted methodology (integration of changes of over 5-hectare areas). The effect of the procedure was the generation of a new database of land cover level 3 (CLC-2006A). The next step of the analyses was the elaboration of a detailed statistical analysis comprising the comparison of databases CLC-2006 and CLC-2006A. The conducted analyses have shown that adopted different levels of detail in designating cover forms result in different levels of content generalization, both in number of divisions and in areas of particular land cover forms. In the CLC-2006A base the number of registered polygons is larger than in the CLC-2006 base. Their number has risen from 4340 to 4495, out of which 135 are between 5 and 25 hectares and which were not included in CLC-2006 base. A multi-directional process of changes within the areas of particular divisions has also taken place. Some land cover forms have grown in size: industrial or commercial territories (121), locations of open pit mines (131), building sites (133), farming territories with a large share of natural vegetation (243) and forests in the state of change (324). The results of the analyses indicate the validity of reinterpreting basis CLC-2006, which can largely improve level of detail of conducted analyses, especially in evaluating areas of land cover forms and in index analyses, e.g. in the determination of urbanization, forest area and population distribution indexes.

Opis:
The real estate cadastre is the primary source of information on land use. It re cords information related to the division of land into types based on the actual way of land use or development. The distinguished types of land use depend on many geographical factors, as well as historical and economic conditions. The study presents a comparison of the detail of land use classification registered in the real estate cadastre in areas functionally related to the urban areas of 9 European countries: Austria, Bulgaria, the Czech Republic, Estonia, Spain, Lithuania, Luxembourg, Germany and Poland. The research concerned the determination of the degree to which the classification of land use in urbanized areas is detailed, whether the studied European countries are characterized by the same number of distinguished classes of ob jects at different levels of detail, and what percentage are the distinguished classes of land use objects in urbanized areas in relation to all of the distinguished classes of objects land use at different levels of detail of classification. The study used legal acts regulating land use issues which have been made available in national languages by government institutions.

Opis:
The article deals with the research on the quantitative classification of land use, which directly affects the amount of land use data collected in the real estate cadastre. For the purpose of this article, the cadastral systems of seven European countries – Austria, Bulgaria, Estonia, Spain, Lithuania, Germany and Poland – have been examined, taking into account how detailed is the classification in agricultural and forest areas. The research covered the provisions of legal acts applicable in the researched seven European countries and made available in national languages by the government bodies. The article asks the following three questions: 1) whether the researched countries adopted the same approach to isolating classes of items related to agricultural and forest areas; 2) whether the researched countries feature the same number of classes of items recorded at various levels of detail; 3) what is the percentage of the distinguished item classes of land uses in the agricultural and forest areas in relation to all of the distinguished item classes at all the levels of detail. The conducted research can be used as a material supporting works consisting of the modernization of the functioning of land registration in the real estate cadastre in Poland.

The objective of this paper is the assessment of the share of individual land cover categories in centric and ring-shaped evaluation polygons. In the analyses the data from the Corine Land Cover project for 2006 and 2012 were used. These data are available through the Urban Atlas. The basic spatial statistics concerning the land cover categories were determined. As a result of the analyses, information about land cover changes that took place over a period of 6 years was obtained, observed with increasing distance from the assumed reference point. An inference was also made regarding the possibility of determining the changes taking place in selected units in the period of 2006–2012.

Celem pracy była analiza pokrycia terenu i jego zmian w województwie łódzkim w latach 2000–2018. Bazując na danych CORINE Land Cover oraz wykorzystując narzędzia GIS, wykonano analizę pokrycia terenu i jego zmian dla trzech przedziałów czasowych 2000–2006, 2006–2012 i 2012–2018, w ujęciu ilościowym i przestrzennym, co pozwoliło na scharakteryzowanie pokrycia terenu badanego obszaru oraz uchwycenie kierunków zmian, ich natężenia i miejsca występowania. W badaniu przeprowadzono pomiar gęstości zmian metodą estymacji rozkładu gęstości z wykorzystaniem nieparametrycznych estymatorów jądrowych (kernel function).
The aim of the author was to analyse land cover and its changes in the Łódź Voivodeship in the years 2000–2018. Based on CORINE Land Cover data and using GIS tools, analysis of land cover and its changes were performed for three intervals – the years 2000–2006, 2006–2012 and 2012–2018 – in spatial and quantitative terms. This approach allowed the land cover of the studied area to be characterised and the directions, intensity and spatial distribution of changes to be captured. In the study the density of changes was measured using the method of density distribution estimation with the use of non-para-metric nuclear estimators – the kernel function.

Opis:
The basin of the Służewiecki Stream, hydrologically uncontrolled, is urbanised, but it has a mosaic-like character, consisting of urban and agricultural land use. This is shown by the graph of the basin and its subcatchments that takes into account the changes of the runoff coefficient in its subcatchments. The land cover changes in 1993–2002 and the forecast for the years until 2012, together with the calculated rainfall hyetograph are input elements to the rainfall-runoff model. The isochrone method with the Kirpich equation constitute the transforming function, and the runoff hyetographs are the output elements from the system. The paper presents also practical problems occurring in the implementation of the recommendations of the local spatial plan as well as consequences resulting from disregarding the recommendations.
Niekontrolowana hydrologicznie zlewnia Potoku Służewieckiego o powierzchni zlewni wynoszącej 55 km2 jest w 51% zurbanizowana. Charakteryzuje się nadal mozaikową strukturą użytkowania miejskiego i rolniczego. Obrazuje to wykres trójkątny rozwinięcia zlewni (dopływy prawe i lewe) uwzględniający zmiany współczynnika odpływu w zlewniach cząstkowych. Zmiany użytkowania w latach 1993–2002 i ich prognoza do 2012 roku (z planu zagospodarowania przestrzennego) wraz z obliczonym metodą Bogdanowicz (1998) hietogramem opadu są elementami wejścia do modelu opad-odpływ. Metoda izochron połączona ze wzorem Kirpicha jest funkcją transformującą, a hydrogramy odpływu są elementami wyjścia z systemu. Zmiany użytkowania terenu w latach 1993–2012 obejmą 10% powierzchni zlewni. Spowoduje to ok. 25% wzrost przepływu maksymalnego wywołanego opadem trwającym, zarówno 3 godziny (14–18 m3/s), jak i 8 godzin (16–20 m3/s).

Opis:
Ostatnie 25 lat w Polsce cechują duże zmiany społeczno-gospodarcze, wyraźnie widoczne także w pokryciu i użytkowaniu terenu. W artykule przedstawiono charakterystykę ilościową, jakościową oraz przestrzenną zmian w pokryciu terenu, jakie zaszły w Polsce w latach 1990-2012, ze szczególnym zwróceniem uwagi na okresy: 1990-2000, 2000-2006 oraz 2006-2012. Analizy zostały wykonane na podstawie danych zgromadzonych w bazach CORINE Land Cover. Podstawowym celem badań była ocena zmian pokrycia terenu, które są następstwem zmian sposobu użytkowania ziemi w Polsce w okresie transformacji systemowej na przełomie XX i XXI wieku. Szczegółowo przeanalizowano przejmowanie gruntów rolnych i leśnych na budowę dróg oraz powiększanie terenów zabudowanych. Otrzymane wyniki pokazują, że powierzchnia zmian była stosunkowo niewielka i w żadnym z analizowanych okresów nie przekroczyła 1% powierzchni kraju. Zaobserwowano, że od 1990 roku następuje systematyczne zwiększanie terenów antropogenicznych głównie kosztem terenów rolniczych (gruntów ornych, sadów i plantacji oraz łąk i pastwisk) i zalesionych.
The last 25 years in Poland are characterized by large socio-economic changes, clearly visible in the land cover. The article presents quantitative, qualitative and spatial characteristics of land cover changes in Poland in the years 1990-2012, with special attention paid to the periods 1990-2000, 2000-2006 and 2006-2012. The analyses base on CORINE land Cover data. The main objective of the study was to analyze the urbanization and accompanying land take of agricultural lands and forest for the construction of roads and the spread of built-up areas. The results show that the area of land cover changes was relatively small and it does not exceeded 1% of the country's territory. Since 1990 a systematic increase in anthropogenic areas is observed which is accompanying with afforestation, and decrease of arable lands.

Opis:
Badania wykonano w ośmiu przekrojach zlokalizowanych na sześciu małych rzekach wyżynnych odwadniających centralne partie Gór Świętokrzyskich, tj. Lubrzance, Gawlicy i Belniance (zlewnia Nidy) oraz Psarce, Czarnej Wodzie i Pokrzywiance (zlewnia Kamiennej). Zlewnie badanych rzek charakteryzował zróżnicowany udział poszczególnych form pokrycia terenu. Dominowały użytki rolne i lasy, a udział zabudowy był niewielki. W półroczu zimowym od XI 2015 do IV 2016 r. w cyklu miesięcznym wykonywano badania terenowe i analizę pobranych próbek wody. Oznaczano temperaturę, pH, przewodność elektrolityczną, stężenie tlenu rozpuszczonego, wodorowęglanów i głównych jonów. Stwierdzono, że najbardziej stabilną pod względem dynamiki stężeń większości jonów jest Czarna Woda o zlewni w ponad 80% pokrytej lasami. Największe wahania odnotowano w wodach Psarki w profilu Trzcianka z największym udziałem użytków rolniczych. Stwierdzono istotne dodatnie korelacje pomiędzy stężeniami HCO3 – i NO3 – a udziałem terenów antropogenicznych w zlewni. Stężenia NO2 – i NO3 – były istotnie pozytywnie skorelowane z powierzchnią terenów rolnych. Zwiększony udział lasów wpływał ujemnie na wartość pH, stężenie HCO3 –, Mg2+, NO2 – i NO3 –. Wskazano także na oddziaływanie punktowych i liniowych źródeł zanieczyszczeń na chemizm badanych rzek.
The research was conducted in eight sections located on six small upland rivers, flowing from the central part of the Świętokrzyskie Mountains: Lubrzanka, Gawlica and Belnianka (in the Nida River drainage basin) and Psarka, Czarna Woda and Pokrzywianka (Kamienna River drainage basin). The catchment areas of researched rivers had diversified forms of land use, with dominating arable lands and forests and small share of housing. From November 2015 to April 2016 field studies were conducted and water samples collected once a month. The following parameters were analysed: temperature, pH, conductivity, dissolved oxygen, hydrogencarbonate and concentration of major ions. The river with most stable ion concentrations was Czarna Woda, with catchment area covered in over 80% with forests. The greatest fluctuations were noted on Psarka in profile Trzcianka, gathering water from arable lands. There was a significant positive correlation between the concentrations of HCO3 – and NO3 – ions and the share of anthropogenic areas in river basins. The concentrations of NO2 – and NO3 – were positively correlated with the area of agricultural lands. Higher share of forests negatively affected the pH value and concentration of HCO3 –, Mg2+, NO2 – and NO3 –. The results also suggest the impact of point and line sources of pollution on the physicochemical properties of the analysed rivers.

Przedmiotem badań była ocena sekwestracji węgla, jako popularnego wskaźnika regulacyjnych świadczeń ekosystemowych, przy użyciu dwóch baz pokrycia terenu – Urban Atlas (UA) i Corine Land Cover (CLC). Badania objęły zachodnią strefę miejską i podmiejską Warszawy z fragmentem Kampinoskiego Park Narodowego (gminy Stare Babice, Izabelin, Łomianki i dzielnice Warszawy – Bemowo, Bielany). Wyniki świadczą, że dane CLC i UA nie są wystarczającym materiałem kartografiznym do oceny świadczeń ekosystemowych w skali lokalnej. Opracowywanie planów przestrzennego zagospodarowania na poziomie gmin lub ich fragmentów, powinno opierać się na badaniach terenowych, których celem będzie weryfikacja danych UA i CLC. Należy również wykorzystywać wskaźniki, które nie bazują bezpośrednio na danych UA i CLC.

Opis:
Over the years, Cameron Highlands have witnessed extensive land-use and land-cover (LULC) changes due to the massive agricultural and urbanization activities. This significantly contributed to the erosion problems in the area. Rainfall erosivity that measures the aggressiveness of raindrop in triggering soil erosion is one of its major components that could be influenced by the LULC changes in watersheds. However, the research relating to the LULC changes with the erosivity especially in the complex landscape is scarce. Hence, this study applies geographic information system (GIS) and remote sensing techniques to assess the LULC changes and their influence on the rainfall erosivity distribution in mountainous watershed of Cameron Highlands. Four Landsat images and the rainfall data from the period of thirty years were analysed for the development of LULC and erosivity maps respectively in ArcGIS environment. The study showed that the study area experienced immense land-use changes especially in agriculture and urbanization which affected the erosivity distribution. The LULC change for agriculture increased linearly in the last 30 years from 7.9% in 1986 to almost 16.4% in 2016. The results showed that urban development increased from 5.1% in 1986 to 11.4% in 2016. The increasing urbanization trend was targeted to meet up with tourism requirement in Cameron Highlands. However, forest class declined tremendously due to the exploration of land for agriculture practice and other various types of development. Watershed managers and other stakeholders should find this study beneficial in tackling erosion and its associated ecological challenges.

Opis:
Aktualne mapy pokrycia terenu są podstawą wielu dyscyplin nauki oraz mają szerokie zastosowanie aplikacyjne. Jednym z problemów aktualizacji map jest proces aktualizacji danych. Teledetekcja dostarcza codziennie nowych zobrazowań satelitarnych, które mogą zaspokoić potrzeby aktualizacji baz danych. W niniejszym artykule autorzy przedstawiają metodę klasyfikacji pokrycia terenu sztucznymi sieciami neuronowymi fuzzy ARTMAP zgodnie z założeniami i legendą Corine Land Cover na podstawie danych satelitarnych Landsat, które wykorzystywane są do opracowania map pokrycia terenu. W artykule użyto jako danych referencyjnych i weryfikacyjnych najnowszą mapę Corine Land Cover (CLC) 2012. Do przeprowadzenia klasyfikacji symulatorem wykorzystano trzy zdjęcia satelitarne Landsat TM (21.04.2011, 05.06.2010, 27.08.2011). Obszarem badań były okolice Warszawy. Wynikami pracy symulatora są mapy klasyfikacji pokrycia terenu oraz macierze błędów klasyfikacji. Uzyskane wyniki potwierdzają, że sztuczne sieci neuronowe mogą z powodzeniem być wykorzystywane do aktualizacji map pokrycia terenu.
Modern land cover maps are the basis of many scientific disciplines and they are widely applied. One of the problems connected with the revision of maps is the data updating procedure. Remote Sensing daily provides us with the new satellite images, that can meet the needs of database updates. In this article the method of classification for land cover with the artificial, neural, fuzzy ARTMAP networks is presented by the authors in accordance with the objectives and legend of the CORINE Land Cover Map on the basis of the Landsat satellite data, which are used to elaborate the land cover maps. The latest CORINE Land Cover map 2012 polygons are used as the reference and verification data. Three satellite Landsat TM images of 21.04.2011, 05.06.2010, 27.08.2011 are processed by a fuzzy, artificial, neural network classificatory simulator. The area of research was Warsaw and its surrounding area. The results of this research are the classificatory land cover maps and error matrices. Acquired results confirm that the artificial neural networks can be successfully used for land cover updating.

Increasing urbanization results in constant enlarging of the artificial area closed to water infiltration. In 2006–2008, the Soil Sealing Enhancement (SSE) database was the part of the GMES Fast Track Service on Land Monitoring. The accuracy of the final product set by the authors should reach at least 85%. Orthorectified high resolution aerial photos of Poland were used to develop reference data constituting 20,000 random samples around the country. In each sample, the points were classified into three possible surface classes: natural, artificial and semi-sealed. Comparison of reference data to original project statistics revealed the values of accuracy, commission and omission errors in the SSE dataset. Although, SSE accuracy in Poland fulfils the criteria set by SSE authors with overall accuracy of 99.5%, the individual analysis for each category reveals many weaknesses. Preliminary interpretation of mistakes leads to the conclusion that the spatial resolution of pictures used in the SSE project is insufficient. In several cases, validation proved that omission errors were made in relation to construction sites or recently constructed buildings. It should be stated that the accuracy of SSE product for Poland should be treated as the maximum value of impervious surfaces.

Opis:
Quantifying and understanding global land use change and its spatial and temporal dynamics is critical to supporting international policy debates. The main area of transformation of spatial structures nowadays are suburban areas of the largest cities. Constant land development and urbanization, including such forms as urban sprawl, influence significant changes in land use. The aim of this study was to analyse a land use change pattern in a selected rural area which is under pressure of spatial development of a regional city. Data used for a land use change detection was based opensource Urban Atlas dataset for 2006, 2012, and 2018, enriched by recent update from 2021 orthophoto map. Spatial analyses presenting statistics of land use change were conducted in QGIS. Besides analysis of land use change, the paper discusses observed spatial patterns also taking into account changing social, environmental and economic conditions and spatial policies influencing land cover complexity. Understanding these dynamics would help better spatial management of real estates for more sustainable land development.

Opis:
Agricultural land covers more than half the area of metropolitan areas in Poland, and is therefore particularly prone to the influences of the processes associated with their development. The aim of the study was to analyse changes in agricultural land cover within the metropolitan areas of Poland for the years 1990–2012; and to capture their dynamics, types and directions. The percentage share of the total study area, for each of the forms of agricultural land cover and their changes were traced, with the spatial distribution of the changes also being determined. The results of the study show that in metropolitan areas, agricultural land cover is undergoing transformations that do not result in the loss of agricultural lands, or that involve a decrease in surface area due to their change into anthropogenic forms of land cover. The greatest transitions occurred between 2000 and 2006 and were observed in the outer zones of metropolitan areas.

Using Corine Land Cover to predict habitats occupied by moose Alces alces. The aim of the study is to assess the possibility of predicting the habitats occupied by moose on the basis of Corine Land Cover. The second aim was to assess whether the impact of the structure of land cover on the population density of moose can change over time with an increase in population numbers. The data for analysis was the number of moose in 293 hunting districts assessed each year in spring in Podlaskie Voivodship. The data covered ten years from 2010 to 2019. The boundaries of each hunting district were compared to the Corine Land Cover layer, and the share of each type of coverage was calculated. The impact of cover types on moose numbers was analyzed in generalized linear models. The moose population showed a distinct increase of population numbers over the last 10 years in the Podlaskie Voivodship. In all the analyzed years, four cover types explained the distribution of moose. The numbers of moose decreased along with the increasing share of arable lands, but was positively related to the presence of inland marshes and share of deciduous forest. In 2010 and 2011, additionally two cover types explained the distribution of moose in the models, similarly in 2019. Obtained results show that the current range of moose in the Podlasie Voivodeship allows the reliable prediction of its numbers on the basis of Corine Land Cover. Impact of some cover types has changed with time.

Good understanding of relations between historical land cover changes and accompanying environmental components should be a starting point for landscape modelling and forecasting its future patterns. Analysis presented here focuses on the relationships between chosen environmental conditions and agricultural land cover changes in the period of over 150 years. The study area consisted of fragments of Nidziańska Basin and South Pomeranian Lake District macroregions. The land cover data was derived from a number of archival and contemporary topographical maps. Long-term changes of land cover were then related to underlying landscape elements (geological deposits and morphometric landforms). With the help of canonical analysis major correlations were identified and described.

The analysis was made on the basis of data from topographic maps on a scale of 1:10,000 and digital data from BDOT10k for a period of 28 years. In the areas of major changes, the scale and directions of changes between particular types of land cover were determined. Negative natural effects expressed, among other things, by the deteriorating proportion between the biologically active and built-up areas were indicated.

The aim of this research was to present the land cover structure and landscape diversity in the West Polesie Biosphere Reserve. The land cover classification was performed using Object Based Image Analysis in Trimble eCognition Developer 8 software. The retrospective land cover changes analysis in 3 lake catchments (Kleszczów, Moszne, Białe Włodawskie Lakes)was performed on the basis of archival aerial photos taken in 1952, 1971, 1984, 1992, 2007 and one satellite scene from 2003 (IKONOS).On the basis of land cover map structure, Shannon diversity index was estimated with the moving window approach enabled in Fragstats software. The conducted research has shown that the land cover structure of the West Polesie Biosphere Reserve is diverse and can be simply described by selected landscape metrics. The highest level of land cover diversity, as showed by Shannon Diversity Index, was identified in the western part of the West Polesie Biosphere Reserve, which is closely related to the agricultural character of land cover structure in those regions. The examples of three regional retrospective land cover analyses demonstrated that the character of land cover structure has changed dramatically over the last 40 years.

Opis:
Land cover change is the result of complex interactions between social and environmental systems which change over time. While climatic and biophysics phenomena were for a long time the principal factor of land transformations, human activities are today the origin of the major part of land transformation which affects natural ecosystems. Quantification of natural and anthropogenic impacts on vegetation cover is often hampered by logistical issues, including (1) the difficulty of systematically monitoring the effects over large areas and (2) the lack of comparison sites needed to evaluate the effect of the factors. The effective procedure for measuring the degree of environmental change due to natural factors and human activities is the multitemporal study of vegetation cover. For this purpose, the aim of this work is the analysis of the evolution of land cover using remote sensing techniques, in order to better understand the respective role of natural and anthropogenic factors controlling this evolution. A spatio-temporal land cover dynamics study on a regional scale in Oranie, using Landsat data for two periods (1984–2000) and (2000–2011) was conducted. The images of the vegetation index were classified into three classes based on Normalized Difference Vegetation Index (NDVI) values and analysed using image difference approach. The result shows that the vegetation cover was changed. An intensive regression of the woody vegetation and forest land resulted in -22.5% of the area being lost between 1984 and 2000, 1,271 km2 was converted into scrub formations and 306 km2 into bare soil. On the other hand, this class increased by around 45% between 2000 and 2011, these evolutions resulting from the development of scrub groups with an area of 1,875.7 km2.

The key objective of the study is to analyse structural characteristics of the landscape from the viewpoint of the structure’s durability, characteristics and speed of change. The research focused on the area surrounding Płock. In the analysed period (1987-2010) slight changes were detected with regard to the land cover, though they were significant in terms of the natural environment. No single dominant process determining land cover change was identified. Fluctuations prevailed (producing a slightly different picture in each microregion), with a fixed pattern maintained. Distribution, shape and spatial location of land cover types are only partly determined by land lie and habitat quality. Fragmentation of the terrain is relatively high, which reflects intense land use, at the same time indicating opportunities to preserve the wildlife and vegetation typical for agrocenoses.

The results revealed an increase in artificial surfaces, with the highest value during the period 2006–2012 (86.56 km2). In total, during the period 2006–2018, the growth in urbanised area amounted to 95.37 km2. The 2024 prediction showed that artificial surfaces increased by 9.19 km2, resulting in a decline in agricultural land.

Actual land cover maps are a very good source of information on present human activities. It increases value of actual spatial databases and it is a key element for decision makers. Therefore, it is important to develop fast and cheap algorithms and procedures of spatial data updating. Every day, satellite remote sensing deliver vast amount of new data, which can be semi-automatically classified. The paper presents a method of land cover classification based on a fuzzy artificial neural network simulator and Landsat TM satellite images. The latest CORINE Land Cover 2012 polygons were used as reference data. Three satellite images acquired 21 April 2011, 5 June 2010, 27 August 2011 over Warsaw and surrounding areas were processed. As an outcome of classification procedure, the maps, error matrices and a set of overall, producer and user accuracies and a kappa coefficient were achieved. The classification accuracy oscillates around 76% and confirms that artificial neural networks can be successfully used for forest, urban fabric, arable land, pastures, inland waters and permanent crops mapping. Low accuracies were obtained in case of heterogenic land cover units.

Accurate high temporal resolution data is a very important source of information for understanding processes in the landscape. High temporal and spectral resolution data enable the monitoring of dynamic landscape processes. For this reason, since 2008 a receiving station for Metosat, NOAA and Envisat data has been installed at the Department of Applied Geoinformatics and Cartography, Faculty of Science, Charles University in Prague. The aim of this study is to analyse the spectral characteristics of vegetation using MERIS data in the Czech Republic. Spectral characteristics of vegetation were examined both by analysing changes in reflectivity as well as by utilising vegetation indices. Vegetation in forests and agricultural land was evaluated. The results present the spectral characteristics of selected associations of vegetation based on MERIS data and a discussion of the methods of multitemporal classification of land cover.

Recently, Google Earth Engine (GEE) provides a new way to effectively classify land cover utilizing available in-built classifiers. However, there have a few studies on the applications of the GEE so far. Therefore, the goal of this study is to explore the capacity of the GEE platform in terms of land cover classification in Dien Bien Province of Vietnam. Land cover classification in the year of 2003 and 2010 were performed using multiple-temporal Landsat images. Two algorithms – GMO Max Entropy and Classification and Regression Tree (CART) integrated into the Google Earth Engine (GEE) platform – were applied for this classification. The results indicated that the CART algorithm performed better in terms of mapping land use. The overall accuracy of this algorithm in the year of 2003 and 2010 were 80.0% and 81.6%, respectively. Significant changes between 2003 and 2010 were found as an increase in barren land and a reduction in forest land. This is likely due to the slash-and-burn agricultural practice of ethnic minorities in the province. Barren land seems to occur more at locations near water sources, reflecting the local people’s unsuitable farming practice. This study may provide use-ful information in land cover change in Dien Bien Province, as well as analysis mechanisms of this change, supporting environmental and natural resource management for the local authorities.

The work presented here aims at developing cover mask for monitoring forest health in Poland using remote sensing data. The main objective was to assess the impact of using the mask on forest condition monitoring combined with vegetation indices obtained from long-term satellite data. In this study, a new mask developed from the CORINE Land Cover 2012 (CLC2012) database is presented and its one-kilometer pixel size matched to low-resolution data derived from SPOT VEGETATION satellite registrations. For vegetation mapping, only pixels with a cover ≥50% of broad-leaved and mixed forests defined by CLC2012 were taken into account. The masked pixels were used to evaluate spatial variability in eight Natural-Forest Regions (NFRs). The largest coverages by masked forests were obtained in Sudetian (65.7%), Carpathian (65.9%) and Baltic (51.3%) regions. For other forest regions the coverage was observed to be around 30–50%. Time-series of the Normalized Difference Vegetation Index (NDVI) comprising SPOT VEGETATION images from 1998 until 2014 were computed and cross-comparison analyses on ≥50% and <50% forest cover masks brought up frequent differences at a level higher than 0.05 NDVI in seven out of eight NFRs. An exception is the Sudetian region, where the data was highly consistent. Furthermore, the Mann-Whitney U non-parametric test revealed statistically significant differences in two regions: Baltic and Masurian-Podlasie NFR. The comparative analysis of NDVI confirmed that there is a need for additional investigation of the quality of newly developed forest mask combined with vegetation and meteorological data.

Opis:
Many cities in developing countries are experiencing ecosystem modification and change. Today, about 10 million hectares of the world’s forest cover have been converted to other land uses. In Nigeria, there is an estimated increase of 8.75 million ha of cropland and decrease of about 1.71 million ha of forest cover between 1995 to 2020, indicating that Nigeria has been undergoing a wide range of land use and land cover changes. This paper analyses the changes in land use/cover in Ila Orangun, Southwestern, Nigeria from 1986 to 2018, with a view to providing adequate information on the pattern and trend of land use and land cover changes for proper monitoring and effective planning. The study utilized satellite images from Landsat 1986, 2002 and 2018. Remote sensing and Geographical Information System techniques as well as supervised image classification method were used to assess the magnitude of changes in the city over the study period. The results show that 26.36% of forest cover and 44.48% of waterbody were lost between the period of 1986 and 2018. There was a rapid increase in crop land by 365.7% and gradual increase in built-up areas by 103.85% at an annual rate of 3.25%. Forest was the only land cover type that recorded a constant reduction in areal extent. The study concluded that the changes in land use and land cover is a result of anthropogenic activities in the study area.

Our ecosystem, particularly forest lands, contains huge amounts of carbon storage in the world today. This study estimated the above ground biomass and carbon stock in the green space of Bilbao Spain using remote sensing technology. Landsat ETM+ and OLI satellite images for year 1999, 2009 and 2019 were used to assess its land use land cover (LULC), change detection, spectral indices and model biomass based on linear regression. The result of the LULC showed that there was an increase in forest vegetation by 12.5% from 1999 to 2009 and a further increase by 2.3% in 2019. However, plantation cover had decreased by 3.5% from 1999–2009; while wetlands had also decreased by 9% within the same period. There was, however, an increase in plantation cover from 2009 to 2019 by 2.1% but a further decrease in wetlands of 4.3%. Further results revealed a positive correlation across the three decades between the widely used Normalized Differential Vegetation Index (NDVI) with other spectral indices such as Enhance Vegetation Index (EVI) and Normalized Differential Moisture Index (NDMI) for biomass were: for 1999 EVI (R2 = 0.1826), NDMI (R2 = 0.0117), for 2009 EVI (R2 = 0.2192), NDMI (R2 = 0.3322), for 2019 EVI (R2 = 0.1258), NDMI (R2 = 0.8148). A reduction in the total carbon stock from 14,221.94 megatons in 1999 to 10,342.44 megatons 2019 was observed. This study concluded that there has been a reduction in the amount of carbon which the Biscay Forest can sequester.

In order to analyze the impact of land use and land cover change on land surface temperature (LST), remote sensing is the most appropriate tool. Land use/cover change has been confirmed to have a significant impact on climate through various aspects that modulate LST and precipitation. However, there are no studies which illustrate this link in the Fez-Meknes region using satellite observations. Thus, the aim of this study was to monitor LST as a function of the land use change in the Saïss plain. In the study, 12 Landsat images of the year 2019 (one image per month) were used to represent the variation of LST during the year, and 2 images per year in 1988, 1999 and 2009 to study the interannual variation in LST. The mapping results showed that the land use/cover in the region has undergone a significant evolution; an increase in the arboriculture and urbanized areas to detriment of arable lands and rangelands. On the basis of statistical analyses, LST varies during the phases of plant growth in all seasons and that it is diversified due to the positional influence of land use type. The relationship between LST and NDVI shows a negative correlation (LST decreases when NDVI increases). This explains the increase in LST in rangelands and arable land, while it decreases in irrigated crops and arboriculture.

Coal is one of the most mining commodities to date, especially to supply both national and international energy needs. Coal mining activities that are not well managed will have an impact on the occurrence of environmental damage. The present study was undertaken to analyze the process of humaninduced landscape transformation in the coal mines affected areas of Cam Pha, northeast Vietnam by interpreting temporal remote sensing data and using Geographic Information System. This experiment revealed that most of the study area was dominated by forest in all the time sequence period. The forest cover has decreased about 21.3%, meanwhile having nine fold increase in mining area from 1990 to 2020. The forest area lost during the study period was 7983.45 ha due to land cover conversion into mining area. The mining activities were also detrimental to the bare land and water body cover. The results of this study are expected to be used to support government efforts and mining managers in post-mining coal activities.

Opis:
The international community affirms the critical role of forests in climate change mitigation, which includes reducing emissions from degradation and deforestation, carbon stock conservation, sustainable forest management, and increasing carbon stocks in developing countries. It relates to land use and land cover changes. This study aims to review land use and land cover changes (LULC) in two decades, namely 2000-2010 and 2010-2020, and the impact on carbon stocks. Landsat satellite imagery in 2000, 2010, and 2020 are classified into six categories: built-up area, cropland, forest, water body, bareland, and grassland. This classification uses supervised classification. The accuracy kappa coefficient values obtained for the LULC 2000, LULC 2010, and LULC 2020 maps were 89.61%, 83.90%, and 87.10%, respectively. The most dominant systematic LULC change processes were forest degradation in 2000-2020; the transition of forest to cropland (349.20 ha), forest to bareland (171.19 ha), and forest to built-up area (661.68 ha). Loss of using the forest for other uses was followed by a decrease in carbon stock. There was a high decrease in carbon stock in the forest category (11,000 Mg C∙y-1). The results showed a significant change in land use and cover. The decline in the area occurred in the forest category, which decreased from year to year. Meanwhile, the built-up area increases every year. Carbon stocks also decrease from year to year, especially forests as the most significant carbon store, decreasing in the area.

Opis:
Since the 1970’s remote sensing enable constant monitoring of land cover and land use, which are considered as the most crucial environmental data. Obtaining this information at global, regional and local scales, becomes the goal of many research and application programs and has allowed for the deeper understanding of the entire Earth system. In December 1999 NASA launched the EOS Terra Satellite, followed in 2002 by Aqua, both equipped with MODIS (Moderate Resolution Imaging Spectroradiometer). Thanks to its technical specification and free distribution of the majority of its products, MODIS is considered to be the most important sensor for the global vegetation mapping. Although has been originally designed for large-scale analysis, MODIS is also used in many regional research programs. This paper presents results of two approaches of multitemporal land cover classification of MODIS data. For the study polygon of 22100 square kilometres, situated in the western Poland, four single day surface reflectance data sets, of spatial resolution of 250m and 500m, were collected for the year 2007 – one for spring and autumn, and two for summer. In the first approach supervised land cover classification was conducted for each set of single day data separately. On the basis of obtained results, final classification was elaborated as an effect of analyse of the sequence of changes for each pixel. In second approach, independent classification was conducted for the aggregation of all possessed data. The accuracy of all classifications’ results was checked against Corine Land Cover 2000 database using 4200 randomly distributed points. Obtained statistics show that comparing with single-day classifications as well as with classification of aggregated data, multi-temporal approach based on the analysis of sequence, enabled crucial improvement of accuracy of the classification.

Opis:
Historical and archival sources are of cardinal importance in landscape research addressing the processes and course of landscape changes in European regions. The Franziscean cadastre from the 19th century is among the most widely used historical sources in Central Europe. We identified 1440 records, finally providing 104 articles reporting the use of the Franziscean cadastre for in-depth analyses in order to identify (i) the practice of the cadastral data processing, (ii) purpose and spatial extent of the study, (iii) use of complementary sources and (iv) particular land use/land cover classes under study. We have found the increasing attention towards the Franziscean cadastre as a source for landscape research reflected by the doubling number of records in the past decade with majority of the case studies located in Czechia (79), followed by Austria (9) and Italy (3). We have identified the trends in the use in landscape trajectory research and application to hydrology, agriculture and forestry. As regards the data processing, several  issues connected with the methodology or design of the records were found (e.g. geographic information system processing description and data source specification). We further problematize the suitability of the supplementary data used and conclude our review with a set of recommendations to contribute to the discussion on the methodology of landscape reconstruction with historical datasets.

Opis:
Despite many studies on the hydrological responses to forest cover changes in micro and mesoscale watersheds, the hydrological responses to forest cover alterations and associated mechanisms through the large spatial scale of the river watershed have not been comprehensively perceived. This paper thus reviews a wide range of available scientific evidence concerning the impacts exerted by the forest removal on precipitation, water yield, stream flow, and flow regimes. It is concluded that there is no statistical correlation between forest cover and precipitation and water yield at the micro and mesoscale. In contrast, there is a relative correlation coefficient (r = 0.77, p < 0.05) between forest cover and water yield at large scales (>1000 km2). These findings help our understanding of the hydrological response to forest disturbance at large and regional scale and provide a scientific perception to future watershed management in the context of human activities and natural hazards.

A flood occurs for many reasons, such as excessive rainfall, runoff coefficient, or an insufficient river channel capacity. The discharge flowing through the floodway depends on the maximum main river dimension that can be normalized. LU/LC changes are affected by runoff discharge, and runoff discharge is affected by the floodway design. The study discusses the effect of land use (LU) or land cover (LC) changes and the design of floodway channel dimensions in the Kali Kemuning watershed, East Java Province, Indonesia. The Nakayasu synthetic unit hydrograph has been used to analyse the runoff discharge, and the Hydrologic Engineering Center’s River Analysis System software analysed the hydraulic properties of river and floodway channels. Results show that the floodway channel design is determined by LU/LC conditions, and the river channel is normalized toward its maximum dimensions. Normalized channel depths and widths vary from 4 to 7 m and 16 to 46 m, respectively. The floodway channel is rectangular, with a bottom width of 10 m and depth of 4.5 m. With the runoff coefficient equal to 0.75, these normalized channel and floodway dimensions are suitable for the flood up to the 100-year return period runoff discharge.

Opis:
Knowledge of a land cover is very essential to understand and know relations between a man and an environment. The land cover is closely related to the rest elements of geographic environment. It also illustrates the variety of the structure of geographic environment. Till the end of the last century, there were no data representing full, reliable and covering the whole country information about the land cover. Maps and studies over this element of landscape were based on other methods of mappings, various scales and spatial ranges. This fact made it impossible to make comparison analysis and to have proper conclusions concerning processes that were taking place. The realization of National Geographic Information Systems (NSIG) and works connected with the creation of CORINE Land Cover (CLC) is a big help in this field. It was impossible without the development of spatial imagery, universality of the application of spatial information systems, and the use of army materials in the civilian, formal cases. Source spatial data used on the paper, mutually supplement and cover one another. Research connected with the analysis of a landscape structure was done in the chosen protected areas in Kujawsko-Pomorskie Voivodeship. All (8) landscape parks were in the Voivodeship. Total area of the preserved territories is almost 12% of the total Voivodeship area, and represent various types of a natural landscape. The structure of the landscape in landscape parks was analyzed with the application of landscape indices. The following indices describing the structure of landscape were calculated and compared: a number of land cover classes, a number of patches, total length of the edge, a shape index, a fractal dimension, and Shannon’s diversity index. Comparisons of indices among parks were done in relation to various scales of source materials.

The suburban areas are lands under strong anthropogenic pressure which results in their significant transformation. Identifying the direction of changes and their intensity is the basis of research based on the analysis of land use and land cover. The study involved the analysis of land cover in the area of suburban zone of the city of Krakow based on the vector geodata available in the European Environment Agency database (Urban Atlas download service). Geographic data were classified according to various categories of coverage. The area was divided into evaluation clusters that included covering buffer zones with the given parameters according to the distance from the city: zones 0–5 km, 5–10 km, 10–15 km and 15–20 km. All analyzes were performed by means of the QGIS software using geoprocessing tools and additional ones of spatial statistics (among other things Group Stats). The percentage of each category of coverage in relation to the total area was made for each of the separate buffer zones’ statements. The theory of changing the structure of coverage categories along with diverging from the city according to the diagram of reducing participation of heavily anthropogenic areas to those less exposed to it was confirmed on the basis of this analysis.

Land surface temperature (LST) estimation is a crucial topic for many applications related to climate, land cover, and hydrology. In this research, LST estimation and monitoring of the main part of Al-Anbar Governorate in Iraq is presented using Landsat imagery from five years (2005, 2010, 2015, 2016 and 2020). Images of the years 2005 and 2010 were captured by Landsat 5 (TM) and the others were captured by Landsat 8 (OLI/TIRS). The Single Channel Algorithm was applied to retrieve the LST from Landsat 5 and Landsat 8 images. Moreover, the land use/land cover (LULC) maps were developed for the five years using the maximum likelihood classifier. The difference in the LST and normalized difference vegetation index (NDVI) values over this period was observed due to the changes in LULC. Finally, a regression analysis was conducted to model the relationship between the LST and NDVI. The results showed that the highest LST of the study area was recorded in 2016 (min = 21.1°C, max = 53.2°C and mean = 40.8°C). This was attributed to the fact that many people were displaced and had left their agricultural fields. Therefore, thousands of hectares of land which had previously been green land became desertified. This conclusion was supported by comparing the agricultural land areas registered throughout the presented years. The polynomial regression analysis of LST and NDVI revealed a better coefficient of determination (R2) than the linear regression analysis with an average R2 of 0.423.

This study presents the information on the dynamics of changes in land use/land cover (LULC) spatially and temporally related to the causes of flooding in the study area. The dynamics of LULC changes have been derived based on the classification of Landsat imagery for the period between 1990 and 2016. Terrain surface classification (TSC) was proposed as a micro-landform classification approach in this study to create flood hazard assessment and mapping that was produced based on the integration of TSC with a probability map for flood inundation, and flood depth information derived from field observation. TSC as the micro-landform classification approach was derived from SRTM30 DEM data. Multi-temporal Sentinel-1 data were used to construct a pattern of historical inundation or past flooding in the study area and  also to produce the flood probability map. The results of the study indicate that the proposed flood hazard mapping (FHM) from the TSC as a micro-landform classification approach has the same pattern with the results of the integration of historical inundation or previous floods, as well as field investigations in the study area. This research will remain an important benchmark for planners, policymakers and  researchers regarding spatial planning in the study area. In addition, the results can provide important input for sustainable land use plans and strategies for mitigating flood hazards.

Timely and accurate detection of land use/land cover (LULC) change is important for the macro and micro level sustainable development of any region. For this purpose, geospatial techniques are the best tool for change analysis as they supply timely, cheaper, precise and up to date information. This paper examines the spatial temporal change trend in LULC in the case of Central Haryana. Landsat 2, 3, 5, 7 and 8 images for the years 1975–2020 for pre and post monsoon periods were analyzed for the study. Radiometric correction was performed to derive better information. ArcGIS 10.2 and ENVI 5.3 are used for thematic layout and thematic change preparation. An unsupervised classification using ERDAS IMAGINE 2015 has also been done to classify study area in eight classes. The year 1975 is considered as the base year for change detection analysis. Results showed an increasing trend for the land use classes of built up, water body, and agricultural land without waterlogging in the pre and post monsoon periods between 1975 and 2020. Remaining land use classes of agriculture with waterlogging, open waterlogged area, vegetation and fallow land/sand dunes decreased during the same period. Increased human activities have changed the LULC in the region and have had a great impact on its sustainable regional development.

W artykule omówiono zagadnienie zwiększenia szczegółowości wydzieleń zawartych w bazach danych opracowanych w ramach programu CORINE Land Cover poprzez zastosowanie mniejszego pola jednostki kartowania i wprowadzenie czwartego poziomu wydzieleń. Porównano zawartość baz danych CORINE Land Cover z nową, szczegółową bazą opracowaną dla powiatu radziejowskiego przy wykorzystaniu tego samego źródła informacji, czyli zdjęć wykonanych przez satelitę Landsat.
The databases prepared within the CORINE Land Cover (CLC) program do not meet the requirements of most national users because of their low spatial resolution. The authors of the article decided to increase this resolution from 25 ha to 2 ha. As the source of information they used the same satellite images which were the basis of CLC database. For an example they chose the area of agricultural Radziejów district (powiat) in central Poland. In CLC-90 base which represents land cover in this region there are 187 polygons with the average size of 324.2 ha representing 13 forms of terrain cover. After having changed the spatial resolution to 2 ha the number of distinguished terrain forms rose to 20. The number of polygons increase to 967 while their average area decreased to 63 ha. In order to make the database more detailed the fourth level of legend was also introduced. It made it possible to increase the number of distinguished forms of terrain cover to 34. A comparison of the data bases prepared for the year 1990 (CLC-90) at the turn of the centuries showed in Radziejów district some minor changes in land cover, which took place on the area of about 147 ha and were represented by only two polygons. At the same time the comparison of detailed data bases showed that those changes covered the area of over 1500 ha and were represented with 297 polygons.

Opis:
Human activities on land have grown significantly changing the entire landscape, while most of the changes have occurred in the tropics. The change has become a serious environmental concern at the local, regional and global scales. The intensity, speed, and degree of land use / land cover (LULC) changes are nowadays quicker compared to the past because of the development of society. Moreover, the rapid increase in population resulted in disturbing a large number of landscapes on the Earth. The main objective of this study was to detect historical (1990-2020) and predicted (2020-2050) LULC changes in the Welmel River Watershed, which is located in the Genale-Dawa Basin, South Eastern Ethiopia. The dataset of 1990, 2005, and 2020 was generated from Landsat 5, Landsat 7 and Landsat 8 respectively to determine the historical LULC map. The result of this study revealed that agriculture/ settlement increased by 6.85 km2 ∙y-1, while forestland declined by 9.16 km2 ∙y-1 over the last 31 years between 1990 and 2020. In the coming 31 years (by 2050), if the existing trend of the LULC change continues, agriculture/settlement land is expected to increase from 290.64 km2 in 2020 to 492.51 km 2 in 2050 at the rate of 6.73 km2 ∙y-1, while forestland is expected to shrink from 690.48 km2 in 2020 to 427.01 km2 in 2050 by a rate of 8.78 km2 ∙y-1.

Opis:
W referacie zostały przedstawione wyniki prac nad określeniem optymalnych metod badania zmian pokrycia terenu i użytkowania ziemi z wykorzystaniem wysokorozdzielczych zdjęć satelitarnych. W trakcie realizacji prac wykorzystano różne typy danych satelitarnych (Landsat TM, SPOT, IRS) w celu porównania ich przydatności dla potrzeb analizy środowiska miejskiego. Przebadano użyteczność różnych metod określania zmian pokrycia terenu, bazujących na cyfrowej analizie zdjęć satelitarnych: porównywania wartości odbicia spektralnego z dwóch terminów rejestracji, porównywania wartości wskaźników zieleni, metodę analizy składowych głównych, metodę analizy wektora zmian, klasyfikację obrazu utworzonego z dwóch terminów rejestracji oraz porównanie wyników niezależnych klasyfikacji. W efekcie wykonanych prac badawczych stwierdzono, że metoda oparta na porównaniu niezależnych klasyfikacji jest najbardziej efektywną dla sporządzania map zmian pokrycia terenów miejskich. Zastosowanie klasyfikacji obiektowej umożliwiło osiągnięcie dokładności wyznaczenia 4 klas gęstości zabudowy rzędu 80%. Analiza wykorzystania różnych typów zdjęć satelitarnych wykazała największą użyteczność do sporządzania map zmian terenów miejskich w przypadku zastosowania połączonych zdjęć wielospektralnych i panchromatycznych z satelity IRS.

Opis:
W artykule przedstawione są pierwsze wyniki klasyfikacji obiektowej zdjęcia satelitarnego średniej rozdzielczości MODIS. Prace wykonano na podstawie dwóch zdjęć zarejestrowanych z pokładu satelity Terra w kwietniu i w sierpniu 2009 r. Przyjęto założenie wykonania równoczesnej klasyfikacji obu zdjęć. Dzięki czemu w procesie rozpoznania można było wykorzystać informacje związane ze zmianami spektralnymi poszczególnych klas pokrycia terenu, które nastąpiły w okresie kilku tygodni. Jako poligon badawczy wybrano fragment zdjęcia obrazujący centralno wschodnią część Polski o powierzchnię 85 267 km2, na którym zobrazowane są podstawowe formy pokrycia terenu występujące w kraju. Danymi wejściowymi są kanały spektralne zakresu promieniowania czerwonego i bliskiej podczerwieni, pierwszego i drugiego zdjęcia MODIS. Dodatkowo wykorzystano kanał PC 2 uzyskany w wyniku zastosowania analizy składowych głównych (PCA). Przyjęte zasady postępowania pozwoliły na rozpoznanie 6 podstawowych klas pokrycia terenu: wody, zabudowa zwarta, zabudowa rozproszona, lasy, tereny rolnicze, łąki. Ocena wyników została wykonana poprzez porównanie klasyfikacji zdjęć MODIS z bazą danych o pokryciu i użytkowaniu ziemi CORINE CLC2006. Całkowita dokładność klasyfikacji została oceniona na poziomie 78%.
The article presents preliminary results of object based classification of multispectral middle resolution MODIS satellite images. In order to use information about spectral diversity of land cover classes, two MODIS Terra images, registered in April and August 2009, were analysed simultaneously. As the study area, a polygon of 85 267 km2 situated in central Poland was selected. Within its borders all typical classes of Polish land cover can be found. The object oriented classification was performed using red and infrared bands of both images. Additionally, channel PC 2 obtained as an outcome of the Principal Component Analysis, was incorporated into the classification as one of the main features for discrimination of land cover classes. The first segmentation is prepared only for classification of water bodies. Next segmentation of the rest of the scene is done, and after that the object domain is divided into two parts characterized by high and low values of PC 2 channel. Using consecutive processes inside the first part of the object domain, the objects were classified as: urban areas, forest and agriculture areas. Grasslands and other agriculture areas are recognized in the second part of the object domain. The applied classification rules, based on threshold values of the bands R, IR, PC 2 and NDVI index, allow detection of six basic land cover classes: water, dense urban areas, spread urban areas, forest, agricultural area and grassland. The accuracy assessment of the final classification was done using the CORINE CLC2006 datasets. Before determining the error matrix, the classification image was re-projected from Sinusoidal into the 1992 coordinate system while the vector data base CLC2006 was exported to the raster format. The overall accuracy was estimated at the level of 78%.

Opis:
Unmanned Aerial Vehicles (UAVs), commonly known as drones are increasingly being used for three dimensional (3D) mapping of the environment. This study utilised UAV technology to produce a revised 3D map of the University of Lagos as well as land cover change detection analysis. A DJI Phantom 4 UAV was used to collect digital images at a flying height of 90 m, and 75% fore and 65% side overlaps. Ground control points (GCPs) for orthophoto rectification were coordinated with a Trimble R8 Global Navigation Satellite System. Pix4D Mapper was used to produce a digital terrain model and an orthophoto at a ground sampling distance of 4.36 cm. The change detection analysis, using the 2015 base map as reference, revealed a significant change in the land cover such as an increase of 16,306.7 m2 in buildings between 2015 and 2019. The root mean square error analysis performed using 7 GCPs showed a horizontal and vertical accuracy of 0.183 m and 0.157 m respectively. This suggests a high level of accuracy, which is adequate for 3D mapping and change detection analysis at a sustainable cost.

Opis:
This paper presents the results of a study on the content of lithogeochemical components (organic matter, Na, K, Mg, Ca, Mn, Fe, Cu and Zn) and grain-size composition of mineral matter in the bottom sediments of Morzycko Lake (Myślibórz Lakeland, NW Poland). This lake is large (342.7 ha) and deep (69 m). The catchment has a typical forested character (mainly in the middle part of the Słubia River valley) with agricultural area (mainly in the upland areas north of the lake). The diversity of concentrations of metals was analysed based on 44 samples from 22 representative sites, including surface sediments and sediments from 5 cm below the current lake bed. The results showed that the chemical composition and granulometry of bottom sediments depends on contemporary morphogenetic processes in the catchment of the Słubia River. Geochemical and grain-size indices varied due to changes in biological productivity, intensity of weathering of postglacial material making up the catchment, and potential for migration of metals to the lake with surface or underground runoff. An important aspect in assessing the degree of enrichment of the sediments in trace elements is the location of shallow parts of the lake near the tourist districts of Moryń.

Opis:
The Lagos Lagoon is under increased pressure from growth in human population, growing demands for natural resources, human activities, and socioeconomic factors. The degree of these activities and the impacts are directly proportional to urban expansion and growth. In the light of this situation, the objectives of this study were: (i) to estimate through satellite imagery analysis the extent of changes in the Lagos Lagoon environment for the periods 1984, 2002, 2013 and 2019 using Landsat-derived data on land cover, Land Surface Temperature (LST), Normalised Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI); and (ii) to evaluate the relationship between the derived data and determine their relative influence on the lagoon environment. The derived data were subjected to descriptive statistics, and relationships were explored using Pearson’s correlation and regression analysis. The effect of land cover on LST was measured using the Contribution Index and a trend analysis was carried out. From the results, the mean LSTs for the four years were 22.68°C (1984), 24.34°C (2002), 26.46°C (2013) and 28.40°C (2019). Generally, the mean LSTs is in opposite trend with the mean NDVIs and EVIs as associated with their dominant land cover type. The strongest positive correlations were observed between NDVI and EVI while NDVI had the closest fit with LST in the regression. Built-up areas have the highest contributions to LST while vegetation had a cooling influence. The depletion in vegetative cover has compromised the biodiversity of this environment and efforts are required to reverse this trend.

Opis:
The calamity windstorm in November 2004 caused dramatic changes of land cover in the Tatra Mountains. The bora have destroyed then more than 12,000 ha of forest and principally affected the habitat structure in the Tatra National Park. The aim of this contribution is to quantify changes in forest fragmentation in 2000 and 2006. We present forest fragmentation maps related to the years 2000 and 2006. The CORINE Land Cover data layers CLC 2000 and CLC 2006 converted to raster format were used as the input data in the process of forest fragmentation assessment. Forest pixels were classified according to fragmentation indices measured within the surrounding landscape as the forest core, forest patch, forest edge, and perforated forest. Decrease of the compact forest areas (forest core) by about 9% was recorded. On the other side, increased percentage of disrupted forest areas was observed. Decrease of the area of the CLC forest classes (classes 311, 312 and 313) on land cover maps from 2000 and 2006 was connected with an increased number of transitional woodland/shrubs polygons (CLC class 324). These results suggest a temporary fragmentation with possible forest regeneration. On the other hand, forest destruction in the National Park facilitated the development of travel and tourism (new hotels, ski parks, etc.). An increased number of construction sites (CLC class 133) indicate that an urban sprawl associated with a permanent forest fragmentation can be also expected in the future.

The main purpose of this work was to assess changes to the forest areas in Promno Landscape Park which occurred in 1830–2013. The assessment of these changes was based on an analysis of cartographic material from 1830, 1890, 1940 and 2013. The article presents the natural and socio-economic conditions in the research area. Analyses of dominant habitats and stands have also been presented together with cartographic material and a detailed analysis and evaluation of the changes over nearly 180 years. Based on the strategic documents and research results, a forecast has also been provided of the changes to be expected in the next dozen or so years. An analysis of changes to the forest areas in Promno Landscape Park has shown that the largest decrease in forest cover occurred in the second half of the 19th century in connection with clear-cut clearings. In 1890, the forest area decreased by 268 ha against 1830. Slight changes took place in the late 19th and the early 20th centuries. In that period, slow afforestation followed logging and therefore the forest area increased from 1,592.3 hectares in 1890 to 1,679 hectares in 1940. Undoubtedly, the largest increase occurred after 1940, after the Second World War when land of poor agricultural value was afforested. The area of forests grew from 1,679 ha in 1940 to 2,545.29 ha in 2013 marking an increase in forest cover from less than 50% to the existing 76%.
