Opis:
Migration has a principal influence on countries’ population changes. Thus, the issues connected with the causes, effects and directions of people’s movements are a common topic of political and academic discussions. The aim of this paper is to analyse the spatial distribution of officially registered foreign migration in Poland in 2012. GIS tools are implemented for data visualization and statistical analysis. Geographically weighted regression (GWR) is used to estimate the impact of unemployment, wages and other socioeconomic variables on the foreign emigration and immigration measure. GWR provides spatially varying estimates of model parameters that can be presented on a map, giving a useful graphical representation of spatially varying relationships.

Opis:
Underground coal mining causes surface changes such as subsidence and land transformation. The knowledge of the character of subsidence in the past and in the present provides useful information for example for spatial development. In this paper the methodology of determining surface height changes based on cartographic modelling in geographic information system (GIS) is presented. It has been applied to two test areas in a former coal basin in the Walbrzych region (SW Poland) that is characterised by complex geological conditions. In the result of a set of interpolation and map algebra operations surface height changes have been determined and the character of subsidence in a period of over 120 years (1886-2009) has been assessed. These results have been compared with the results of predictions based on the empirical Knothe theory of subsidence calculations using spatial statistics parameters. It has been found that theoretical modelling when applied in areas of complex mining and geological conditions produces lower subsidence values and more uniform subsidence surface than the applied method based on actual elevation data. The calculated surface height changes in the analysed period have been presented graphically and described.

Opis:
Geostatistical methods for 2D and 3D modelling spatial variability of selected physicochemical properties of biogenic sediments were applied to a small valley mire in order to identify the processes that lead to the formation of various types of peat. A sequential Gaussian simulation was performed to reproduce the statistical distribution of the input data (pH and organic matter) and their semivariances, as well as to honouring of data values, yielding more ‘realistic’ models that show microscale spatial variability, despite the fact that the input sample cores were sparsely distributed in the X–Y space of the study area. The stratigraphy of peat deposits in the Ldzań mire shows a record of long-term evolution of water conditions, which is associated with the variability in water supply over time. Ldzań is a fen (a rheotrophic mire) with a through-flow of groundwater. Additionally, the vicinity of the Grabia River is marked by seasonal inundations of the southwest part of the mire and increased participation of mineral matter in the peat. In turn, the upper peat layers of some of the central part of Ldzań mire are rather spongy, and these peat-forming phytocoenoses probably formed during permanent waterlogging.

Opis:
The aim of the study was to develop a low-cost method for tourism opportunity spectrum evaluation in rural landscapes. The method uses the geographic information system (GIS) for spatial analysis of the problem. Open source materials are used in the evaluation. Three principal indices derived from spatial data are evaluated: attraction index, view index, and access index. These form the basis for tourism suitability and opportunity spectrum evaluation. The analysis is realized for two types of tourists: those using cars, and hikers. The method permits the current state of tourism to be identified, and points out possible ways for further development as well as identifying valuable but overexploited zones which should be conserved. The obtained results can improve the sustainable management of landscapes and enhance the profits of rural areas.

Opis:
This paper discusses the use of quantitative cartographic methods in the analysis of the undeveloped land properties located in the territory of the municipality of Zakopane. The municipality of Zakopane is a territory with specific ecological, climatic, natural and environmental characteristics. Approximately 60% of the county is covered by the Tatrzański National Park. It comprises many ecological landscape features such as parks, green spaces, and vantage points. The presence of these features increases the value of the property, but at the same time in many cases it creates barriers to the property management arising from the environmental protection. This area is frequently visited by tourists. The market analysis is the first stage of the real estate valuation process. It aims at the identification of the factors influencing the value of real property. The market analysis consists in determining the characteristics of the area where the real property is located and finding the features that have a significant influence on the value of the property. The results of market analysis, the availability and the amount of data may affect the selection of a valuation method. These data refer to the sale and purchase transactions of undeveloped land properties between January 2011 and December 2015. Quantitative cartographic methods were applied in order to demonstrate the importance of the reliable selection of representative real properties and its impact on the acquisition of the information about the real estate market under examination. These methods were also used to investigate the spatial distribution of the transactions and the unit prices of undeveloped land properties. The cartographic analysis was conducted using the ArcGIS software and maps available on the Tatrzański Municipal Geoportal.

Opis:
The article presents data for the prices of good, medium and low land from 1999 to 2012. In addition to the price of land, direct subsidies are also considered. Direct subsidies have been taken into account in accordance with the award period 2004-2012. The data used in this analysis come from the Central Statistical Office (CSO) and from the Agency for Restructuring and Modernization of Agriculture (ARMA). The aim of this study was to compare the diversity of spatial concentration of agricultural land prices in the years 1999-2012, taking the quality of land and direct subsidies into account. In order to obtain spatial concentration of agricultural land prices, the spatial Gini coefficient was calculated. For sake of comparison, the study was also based on the classical Gini coefficient.
Celem pracy było porównanie różnorodności przestrzennej koncentracji cen gruntów rolnych w latach 1999- 2012 z uwzględnieniem jakości ziemi i dopłat bezpośrednich. Do określenia koncentracji przestrzennej wykorzystano współczynnik Giniego uwzględniając odpowiednie wagi przestrzenne. Przedstawiono dane dotyczące cen gruntów rolnych (dobrych, średnich i słabych zgodnie z podziałem GUS) w latach 1999-2012. Uwzględniono także jednolite dopłaty bezpośrednie, które przyznawano latach 2004-2012. Dane wykorzystane do analizy pochodziły z GUS i z ARiMR. Dla porównania różnorodności wykorzystano klasyczne współczynniki Giniego.

The aim of the article is to look at Zamość as a three-dimensional spatial construct, which may be compared to an architectural and sculptural work of art. Analysing the external image of the town, its form, characteristic features, and dominant height one may broaden the interpretation by adding figurative, emotive or metaphysical aspects. The text constitutes the development of the thought of Stanisław Herbst, according to which Zamość was designed as a three-dimensional shape, not as a plan. The subject matter was examined using the sources of historical cartography and iconography along with modern aerial photographs. The text also includes the review of scientific publications concerning the subject matter. The observation of the town also played a major role.

W języku polskim wstępuje wiele synonimów określających „złe duchy”, które w języku potocznym i wielu przypowieściach straszą pod różnymi postaciami. Są wśród nich między innymi: diabeł, czart, strzyga, wampir czy wilkołak. Interesujące może być poszukiwanie odpowiedzi na pytania: Gdzie występują takie nazwy w Polsce? Jakie obiekty geograficzne wskazują? Czy można zauważyć prawidłowości występowania nazw w stosunku do takich klas obiektów jak: miejscowość, obiekt ukształtowania terenu, płynący obiekt wodny, stojący obiekt wodny, inny obiekt fizjograficzny a także ich podklas. Czy istnieje regionalizacja tych nazw w Polsce ? Źródłem informacji o toponimach mogą być mapy i plany analogowe a także współczesne bazy danych i informacje, które można uzyskać na różnego typu portalach internetowych. Do poszukiwania odpowiedzi na postawione pytania wykorzystano bazę danych pozyskaną z Państwowego Rejestru Nazw Geograficznych, którą z wykorzystaniem języka SQL przeszukano pod kątem nazw zawierających wyrazy będące synonimami „złego ducha”. W wyniku badań zostały opracowane mapy: rozmieszczenia toponimów określających „złe duchy” w Polsce oraz mapy gęstości z podziałem na klasy obiektów takie jak: obiekty ukształtowania terenu, inne obiekty fizjograficzne, obiekty wodne i nazwy miejscowości. Wizualizacja przestrzenna danych i analiza statystyczna pozwoliła na uzyskanie odpowiedzi na postawione na wstępie pytania.
In Polish, there are many synonyms describing “evil spirits”, which in common language and many parables are haunting in various forms. They include such names as: diabeł, czart, strzyga, wampir or wilkołak. It may be interesting to look for answers to questions: Where do such names exist in Poland? What geographical objects do they describe? Is it possible to notice any regularity in the occurrence of names in relation to such classes of objects as: town, terrain, flowing water, standing water, other physiographic objects and their subclasses? Is there a regionalisation of these names in Poland? Toponyms can be obtained from maps and analogue plans, as well as from contemporary databases and information available on various types of web portals. In order to find answers to the these questions, a database obtained from the State Register of Geographical Names was used, which was searched using SQL language for names containing words that are synonymous with “evil spirit”. As a result of the research, maps were prepared for: the distribution of toponyms defining “evil spirits” in Poland, as well as density maps with division into classes of objects such as: terrain, other physiographic objects, water objects and place names. Spatial visualisation of data and statistical analysis made it possible to obtain answers to the initial questions.

Opis:
In the economic studies models based on panel data are increasingly used. The standard panel models are composed of a cross-section character of the data in the time, but do not include the interaction associated with the location of objects in the geographic space. Spatial panel models are based on the information contained cross-section data in the time with regard to space. The paper proposes a different approach to the changes in time on the basis of spatial matrix weight. The aim of this study was to show the possibility to apply spatial weights matrix with particular consideration of time. Data for the analysis came from the database of the CSO and the ARMA in period 2004-2012. In addition to working methods of spatial statistics classical taxonomic methods were also used to obtain a distance matrix.

Opis:
Conducting integrated measures within the framework of sustainable development requires an objective identification of the needs for their implementation based on the results of multifaceted analyses of many complex, interrelated factors reflecting the state of the natural environment and the economic and demographic situation. The increasing functionality of Geographic Information Systems (GIS), has made GIS databases a tool supporting the implementation of sustainable development activities. The aim of the study was to recognise the spatial variability of the level of environmental governance in the south-west region of Poland. Methods of research on multidimensional data mining techniques and geo-spatial analyses were applied, resulting in a theoretical model describing the regularities in the relationships between the analysed indicators of environmental governance. The level of environmental governance was most strongly determined by indicators concerning climate change and biodiversity.

Opis:
We investigated the spatial variation patterns of voting results in Polish parliamentary election in 2015 across 380 regions. That election was a milestone event in Polish politics that substantially affected Poland’s internal and foreign policy directions and promoted two emerging political parties as runners-up against the well-established ones. While socio-economic, cultural and geographical factors such as economic activity, historical legacies (post-Russian East vs post-German West) and economic dichotomies (cities vs the countryside) explain most variations for most parties, they do not appeared to fit as determinants of the new parties’ support, especially of right-wing populists. Demographic target groups of individual parties appear to be relatively unresponsive to their pre-election offerings. The spatial specification of econometric models considerably improves their statistical properties. We also examined mixed-W models to account for the unobservable spatial effects stemming from the construction of constituencies. Their distinctive sets of candidates added significantly to the explanation of the spatial variation in voting.

The paper presents the results of numerical calculations of the stability and deformation process of several idealized slopes performed by the elasto-plastic finite difference method, using the commercial codes FLAC3D and FLAC2D. The results of 3D analysis of these slopes are compared with those obtained by the 2D method. The behaviour of slopes of different shapes and inclinations was analyzed. The calculations were carried out for flat, concave and convex slopes inclined at 30°, 45° and 60°, taking into account the influence of the lateral constraints of the slope. Two variants of the medium were analysed, i.e. the mass with no friction and with no cohesion. A comparison of 3D calculation results with those obtained by the 2D limit equilibrium analysis indicates that the 3D approach produces almost always higher safety factors than does the 2D method.
