SOZO database and its cartographic model – a sozological map is a thematic data source that represents the state of natural environment, as well as the causes and effects of both positive and negative transformations occurring in the environment. There is no doubt that the SOZO database should be a tool to investigate and evaluate the state of natural environment in a quantitative manner. However, the analysis of chosen features in the database reveals that they seem to be insufficient for conducting spatial analysis. The crucial problem is related to classes of forest damage represented by point features in a database without the extent of forest degradation. This type of presentation has limited use for geospatial analysis of environment therefore the Authors propose to use remotely sensed data to enhance SOZO database with updated data together with the spatial occurrence of the studied phenomenon. This research presents the potentials of determining class of forest damage based on the vegetation indices (NDVI and NDII) that successfully replaces the point-feature class of forest damage with polygon-based classes, thereby introducing the new quality of the data into the environmental database and make SOZO database a useful product in spatial analysis.
