Geographic information system — tool for digital geodata transformation

The paper discusses the processes typical for the digitization of geoinformation in the GIS information environment. The evolution of the processing of digitized geoinformation by means of GIS is considered. Digital geodata, as experience shows, ensure the improvement of the activities of any company. However, most modern geodata are not interoperable: they are stored in isolated geodatabases, noninteroperable systems, and used in restricted applications. In this connection, it is difficult to exchange geodata; often, it is not possible to analyze and interpret them. The necessity of the existence of geointeroperability for digital transformation of geodata is shown. The existing *models of interoperability used for the formation of GIS are listed. It is noted that the most unexplored problem of GIS is still the elimination of the gap between the various models of interoperability used to form it. Solving this problem would provide a unified method that takes into account the strengths and weaknesses of each individual model when they are integrated.
