    Opis:
    The study discusses the changes in the land cover in the western part of the Zduńska Wola city. The study was based on the analysis of land cover data obtained from aerial photographs taken in years 1933 and 2015. For 82 years, significant changes took place in the city and they were reflected in land cover changes. The study area was covering 3.7 km2 and in the analysed period, the land cover changes took an area of 2.8 km², that is 75,7% of its surface. Changes mainly occurred on the grassy and agricultural areas, which were changed in to artificial surfaces, mainly into builtup areas.

    Opis:
    In the paper, results of the effective rainfall conditions changes analysis between 1944 and 2014 in two urban catchments in Kielce is present. The objective was achieved by detailed land cover changes analysis based on archival US Air Force aerial photographs from 1944 and contemporary ortophoto from 2014. In order to identify the hydrological consequences of land cover changes the Soil Conservation Service Runoff Curve Number (CN) method was used. The analysis was conducted using QGIS and SAGA GIS software. Research has shown major land cover changes in both catchments - decline of arable land and significant increase of impermeable surfaces such as roofs, roads, pavements, parking lots and squares (from 7.5 to 44.3 % of total SI-4 catchment area and from 10.6 to 43.3 % of total SI-5 catchment area). Those changes directly influenced the weighted CN value of the SCS method (from 76 to 80 in SI-4 catchment, from 79 to 82 in SI-5 catchment), finally leading to transform up to 50 % of the total design rainfall (0,01 %) in to the effective rainfall in the catchments.

    Opis:
    The purpose of this paper is to demonstrate suitability of historic aerial photographs for the identification of urban conservation strategies in Poland after World War II. Legal regulations on heritage protection are discussed and the historic photographs - on which urban spatial structures are visible - are compared with modern aerial photographs. The discussed regulations and their social and political contexts led to identification of several practices. Many ? Some towns were viewed as German heritage. There was also a trend to unify and typify construction projects, to change spatial functions of town parts and to eliminate some elements from the town spatial structure. These practices are illustrated by the cases of Brzeg Dolny, Koźmin Wielkopolski, Lubiąż, Sławno, Ścinawa and Śmigiel. Our studies have affirmed that historic aerial photographs are highly suitable for the recording of landscape changes and activities of institutions responsible for urban heritage. They also demonstrate that there has been no devised model of conservation policy in Poland after World War II. The cultural heritage of every town should be approached on its own terms together with individual decisions taken and their social and political contexts.

    Opis:
    The study aimed to offer an analysis of the spatial structure of Białystok in the period 1967–2006. The analysis was made using aerial photographs and a set of cartographic and geodesic data. Białystok is the largest city of north-eastern Poland and the capital of the Podlaskie region. It is ranked second of all Polish regional capitals in terms of population density. Since the 1960s, Białystok has recorded an over twofold increase in the number of its population. The city has both expanded its area and changed its structure (GUS, 2009). We investigated the materials from two years, 1967 and 2006; their choice was based on the availability of materials. Based on the aerial photographs from 1967, J.R. Olędzki prepared a number of maps depicting the structure of Białystok. The findings from this research were presented in the paper entitled “Application of aerial photographs in the study of urbanised areas” (in Polish) and formed the basis for the research relating to the year 1967 (Olędzki, 1981). The most recent aerial photographs of Białystok on the scale 1: 26 000 come from 2006, which allowed for analysing the city’s spatial structure at two points in a period spanning 40 years. Over this period, the city has undergone substantial changes. Our interpretation has proved that aerial photographs can be useful in making analyses of land use changes in the city. For both these years, we analysed the area occupied by the city in 2006, which at that time was 10 212 hectares. We made two separate maps for either year, viz.: “Białystok – spatial structure in 1967”, and “Białystok – spatial structure in 2006”. On their basis, another map was produced: “Białystok – changes in the spatial structure in 1967–2006”. Using geoinformation software (QGIS, ArcMap), we were able to compile statistics to characterise these maps. To prepare the aforementioned maps, we used the following materials: map “Białystok – spatial structure of land use in the city”, map “Białystok and compactness of its development”, aerial photographs, topographic maps, map of the Białystok district from the 1960s, city map and a 3D city development model. In order to prepare the maps, we needed to convert the aerial photographs, which involved finding one system of coordinates for them. The geometrised, colour aerial photographs were subject to a visual interpretation. The photographs which were used were digitalised. The process of interpretation was carried out on a computer screen without using any ready to use patterns. The interpreted objects were drawn on the photographs as separate vector layers, with additionally coded polygons as their corresponding forms of land use. To compare the studies prepared on the basis of aerial photographs from 2006 and 1967, we used the key to the map “Białystok – spatial structure of land use” made by J.R. Olędzki (1981), which was however subject to slight modifications. One of the elements distinguished on the maps was the division of buildings into five categories based on their height. Due to varied source materials for the two years in question, the height analysis was conducted in two ways, and on every such occasions the buildings were divided into categories: buildings to 7 m, buildings to 15 m, buildings to 20 m, buildings to 30 m and buildings taller than 30 m. In order to defi ne the characteristics of land use in 1967, we analysed the map “Białystok – spatial structure in 1967”. The largest area was at the time occupied by forests, meadows and arable land having a total of over 7 000 ha, which accounted for over 70% of the area in question. This can be viewed as a proof of the area’s rural character, which is also corroborated by a large share of low buildings (up to 15 metres). This mainly included dispersed development, with residential and farms buildings as well as backyards. No parkings were shown on the map owing to their small size. A quantitative characteristic of the land use in 2006 is shown on the map “Białystok – spatial structure in 2006” (Fig. 10). The map also shows the buildings in five categories of height. The largest areas were occupied by meadows (over 2 600 ha) and forests (over 2 200 ha), followed by buildings up to 15 metres in height. In order to compare the land use in Białystok in the years 1967–2006, we prepared the map “Białystok – changes of spatial structure in 1967 –2006” (Fig. 14.). This map was drawn on the basis of two maps depicting the city’s spatial structure in 1967 and 2006. The map was produced by intersecting the two aforementioned maps. Then, in order to highlight the changes and make the map easier to read, we removed those polygons where the structure of land use in both years in question was similar. The remaining polygons were depicted in two ways: for 1967 - with colours, and for 2006 – with hatching. Finally, the road and river network valid for 2006 was added. The most significant changes could be seen in the acreage of arable land: in 1967, it occupied 3 991 ha, which accounted for 39.08% of the city’s area, and in 2006 – a mere 561 ha, i.e. 5.49%. This is a proof of the city’s development and the change of its character from rural to urban. Over the past 40 years, the spatial structure of Białystok has changed considerably. In the 1960s, a considerable part of the city’s area within the present administrative boundaries was used as arable land, and urbanised areas made up only 23% of the area of the city. In 2006, nearly half of the area of Białystok was under land use having typically urban functions. The application of aerial photographs and geoinformation methods opens many possibilities offered by such materials and methods in the study of the spatial structure of urbanised areas. They also make it possible to prepare a comprehensive q – quantitative analysis of the areas under research.

    Opis:
    A sozological map is one of the thematic maps and presents the state of the natural environment, as well as causes and effects of both negative and positive transformations occurring in the environment under the influence of miscellaneous processes, including human activity, as well as methods applied in the protection of natural values of this environment. An official sozological map is prepared in the scale of 1:50,000 on a basemap of an available topographic map. The content of an official sozological map consists of a few groups of elements, and the works are carried out in two stages – field mapping and the subsequent editorial preparation. Field mapping is the main stage in the collection of updated thematic data. In 2009, within the scope of an environmental science camp, sozological mapping was done at the scale of 1:10,000 by the Student Scientific Association of Geographers from the Institute of Geography, NCU, and during the subsequent eight months – a digital sozological map of the Gopło Millennium Park (GMP) was prepared. The situational background for that study was a large-scale topographic map at the scale of 1:10,000 with updated situational content from the mid-1980s. GPS receivers were used during the detailed field exploration, and for the revision of situational data and selected elements of the thematic content, digital, panchromatic orthophotomaps from 2004 were used together with their field revision. The research objective was to determine the usefulness of remote-sensing materials in the revision of selected elements of the sozological map’s content together with the collection of updated situational and thematic data. Based on the remotesensing data, the situational content of the map was updated within the scope of important elements of the land cover and land development, together with their course and borders, the road network and industrial lines; certain selected elements of the degradation of the land surface, surface waters and atmospheric air were interpreted and verified. As a result of this study, a digital sozological map was created in the scale of 1:10,000, which was handed over to the GMP Management in the town of Kruszwica.
