There is an extensive amount of research works in the field of land inventory. However, in modern scientific and technical literature, they do not deal with designing a multi-level information base for the inventory of agricultural land, a priority category of land. There is practically no detailed description of the database formation in existing papers. The aim of the work is consistent designing a bank of data for the agricultural land inventory. So, the authors discuss the procedure for carrying it out, provide an analysis of modern technologies in order to form semantic and graphical parts of the information base, and outline the features of its sequential design. The research methods of theoretical and empirical level were used. We have presented the automation for the process of entering data into the base using GIS technologies. As a result, the final outcome was obtained, a multi-level bank for land inventory. The approbation results of the proposed production are presented on the materials of the Pskov oblast.
