ABSTRACT
The paper presents a method for the analysis of spatial distribution of land cover based on data from Topographic GeoDatabase in a nominal scale of 1: 10000 (abbreviation: BDOT10k). The analysis of land cover and its development allow to specify a number of parameters derived from human activities and natural forces. Researchers use a variety of methods for classificationand valuation of areas which have been modifiedfor Poland. The diversity of types and variability of land cover has been presented in a form of an object – vector. An additional aim of this work is the inventory of the condition of the Podkarpackie Province in terms of the location of the areas with varying degrees of ecological features intensity in the mesoregions for future analyzes of land cover changes. The source data have been obtained in GML format and processed into an object-relational SpatiaLite database. The accuracy of geo-referenced boundaries of objects does not exceed 3 meters and was not generalized, which ensures a high degree of reliability of the calculated parameters. This was confirmedby the evaluation of the quality of the data in the BDOT10k database. Geoprocessing methods and spatial relationships in heterogeneous GIS systems were used. The results of the analyzes are presented in a form of spatial data, multi-layered compositions and cartograms. The research was conducted in the area of 17 844 km2 of Podkarpackie Province.
