Keywords GIS – logical data integration – geographical knowledge
Description Technical means reduce format and geometric differences between GIS data layers coming from various sources. By overlaying them many unrealistic combinations of nature, land use, etc. features originate. These should be removed using logical geodata integration based on geographic knowledge. Three logical geodata integrations methods were developed: manual one with posterior digitizing, on-screen vectorizing and automatic one. Fuzzy analysis does not improve the geodata quality.
