Podstawą analizy zmian form użytkowania ziemi w Polsce są najczęściej mapy tematyczne, które opisują użytkowanie ziemi w różnych przekrojach czasowych. W artykule przedstawiono zagadnienia związane z opracowaniem metodyki integracji wieloźródłowych danych kartograficznych, jak również wypracowania zasad prowadzenia analizy porównawczej treści map użytkowania ziemi oraz sposobu wizualizacji kartograficznej wyników badań.

Land use maps can be a basis for studies of changes in land use forms in Poland. Among variety of maps two cartographic materiais are worthy of particular attention. First of these two is land use map prepared in 50's of 20th century by F. Uhorczak. Thematic contents of this map was based on the contents of topographic maps at a scale of 1:100000, prepared before Second World War. Hence, the map presents state of land use in Poland, which was in 30's of last century. Database prepared within CORINE Land Cover 2000 (CLC-2000), containing information on land cover and land use in Poland in 2000, is the second type of map data. High-resolution satellite images collected by Landsat satellite were the source data used for preparation of this database. Different methods of data acquisition and processing, various forms of their recording and visualization, as well as differences in projection and nonuniform rules of generalization create serious problems while comparing these cartographic materials directly. So, in order to make the comparison, feasible data ought to be standardized. This process comprised at first conversion of analogue data to digital ones and next geometrical matching of both sets of data. It implied transformation of scanned small-scale maps to the reference system, which was applied for preparation of CORINE Land Cover 2000 database. Next step was aimed at obtaining both ranges of thematic contents comparable; it led to preparation of rules of thematic aggregation of CLC 2000 database. In order to compare both sets of data preparation of methods of analysis was indispensable. As a result of interpretation the database was prepared, which contains information on changes of land use forms in Poland between 1930 and 2000. This database enabled to determine transfigurations of land use forms and to analyze their multiyear spatial changes in Poland.
