In the paper, the methods for development of relational basis of topographical data and its processing into a form of maps of slopes, exposures and relative intensity of solar radiation, have been presented. The above mentioned process was divided into four stages: -gaining of data on terrain and their processing into a vector farm, -processing of data on terrain into a screen form, -calculation of slopes, exposures and relative intensity of solar radiation in screening system, -presentation of results in a graphical form, i.e. maps. Final results and maps of slopes, exposures and relative intensity of solar radiation will serve a verification of the following borders: agricultural-forest and sod-field.
