The article is devoted to consideration of approaches to determination of priority directions of development of the system of topographic and geodetic support as a component of information support of the Armed Forces of Ukraine (Defense Forces). The main results of the analysis of the experience of conducting anti-terrorist operation, joint operation in the east ofUkraineand the participation of the armed forces of the leading states in the military conflicts of the last decades are presented. Based on the analysis, new requirements for topographic and geodetic support have been established, which puts forward the rapid development of information technologies in the world, in particular, full transition to digital technologies of mapping information creation, use of geo-information technologies for solving problems of terrain analysis and decision support, rapid provision of users with geospatial information for through automated control systems.The basic concepts are structured: geoinformation support, digital mapping information, digital environment model, digital map, electronic map. The main tasks of the geographical information systems of the military purpose for enhancing the combat capabilities of the troops (forces) by improving the information support of the Armed Forces (Defense Forces) are determined. The necessity of development of information technologies and their introduction in the troops (forces), improvement of special software for processing of operational and tactical information for drawing on digital maps of terrain is substantiated. The main aspects of the analysis of the organization of topographic and geodetic support of the Armed Forces of the developed countries of the world, the state of functioning of the information support system of Ukraine to find ways to improve the information support of the Armed Forces.The directions of further improvement of the topographic and geodetic support as an integral part of the information support of the state administration in the military sphere for timely and qualitative satisfaction of geospatial data the Armed Forces (Defense Forces) are widely considered through the widespread introduction of modern geographical information systems.
