The implementation of environmental aspects into the common agriculture practices are expected to be supported with a relevant scientific knowledge and landscape data. Retrospectively it is also important to evaluate the impact of particular environmental (agri-environmental) measures on landscape. Regarding this there is strong requirement on geographical (spatial) data of two important features which are the possibility of their harmonized processing and representation and possibility of their harmonized complementary integration. The aim of presented paper was to identify and to present a unified method of processing various geographical data and to identify unified method of environmental indicators/indexes definition and assessment. In case study several thematically different geographical databases were processed. Reference geographical grids with a spatial resolution of 10x 10 km, 5 x 5 km or 1 x 1 km and spatial analyses in GIS enabled data to be spatially harmonized. The data analyses and environmental indexes assessment in database software enabled data to be thematically harmonized. Along with data harmonization, the specified environmental indexes were statistically compared and the differences between relevant ones were declared. On the base of case study results we confirmed that reference grid represents appropriate tool for different geographic data harmonization and appropriate tool in evaluation the landscape dynamics. Presented method enables to specify new landscape data with high potential in rate and the degree assessment of environmental aspects integration in agriculture.
