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.

The paper deals with problems occurring during the integration of spatial data on geoenvironmental information stored in various thematic databases and map series based on them. The content and data processing technology used for creating the sozological database at the Head Office of Geodesy and Cartography (GUGiK) and the geoenvironmental database at the Polish Geological Institute (PIG) are analyzed, with main focus on their content compatibility and possibilities of integrating the geoinformation from both sources enabling their simultaneous use in spatial analyses. The main advantage of these resources, meant not only as analog maps, but principally as spatial databases, is their applicability for complex analyses employing GIS-based tools. From the end-user point of view, an important feature is thus the ability to integrate spatial data originating from various external sources. Using different basic sets of topographic data, or different vectorisation techniques of analog maps results in different modeling of the same topographic objects (e.g., rivers) into geometric objects in spatial databases of GUGiK, PIG and IMiGW (Institute of Meteorology and Water Management). Direct integration of these data is practically impossible. This problem would be solved by creating a coherent nationwide reference database and using it as the common topographic data source. Besides, at least partial harmonization of conceptual models of the thematic databases would allow to implement an interoperational system allowing joint analysis of the data. The concept of creating the spatial database infrastructure in Poland assumes creating several spatial databases containing basic(topographic or general geographic) reference data that would serve as a common geometric basis for the secondary thematic studies. At present, the Polish National System of Geographic Information (Krajowy System Informacji Geograficznej; KSIG) includes, among others.: General Geographic Databases (Ogólnogeograficzna Baza Danych) . with geometric accuracy as in analog maps in 1: 250,000 scale or less), VMap Level 2 database -with geometric accuracy as in analog maps in 1: 50,000 scale, Topographic Data Base (Baza Danych Topograficznych) . with geometric accuracy as in analog maps in 1: 10,000 scale. Creating a rational concept of SDI in Poland requires not only developing reliable reference databases, but also harmonization of the thematic databases managed by different institutions. Obviously, the state reference system should be the topographic data source for thematic studies. Thus, all presently developed Polish thematic projects of this kind should use as their topographic data source the Map L2 database (currently being updated using ortophotomaps), and later the so-called Topographic Data Base Level Two.

The dissertation has two basic aims, a methodological and a cognitive one. Under the first, the main research task was to work out methods for the assessment of the state of the natural envi-ronment on the basis of a numerical sozological map at a scale of 1:50 000. It included: • devising a system of information about pollution and threats to the natural environment of the given area (features undesirable in terms of the phenomenon studied) as well as its po-tential (features that improve the quality of the phenomenon studied) on the basis of a numerical sozological map; • devising indicators based on the created information system that would allow the envi-ronment to be diagnosed; constructing a synthetic indicator of the state of the natural environment embracing the proposed diagnostic indicators with the help of the research methods offered by multivari-ate comparative analysis, or more precisely, by one of its tools, viz. a synthetic measure of development; and • establishing the values of the synthetic environmental indicator in the study units (com-munes). On the basis of the values of the synthetic indicator a classification of the study units was made to distinguish areas of maximum contrast but a similar state of the natural environment and a similar structure of its synthetic indicators. The classification provided a basis for a spatial diagnosis of the state of the natural environment in the areas distinguished. It embraced both the assessment of this state and its causes, the identification of the most heavily polluted and most seriously threatened environmental components in the study units, and the identification of their potential.
