The author considers the need for evaluation of territories in order to ensure the ecological balance and stability of the environment. It is possible only when all the features of the terrain are known in detail. One of the ways that contribute to high-quality and detailed analysis is three-dimensional mapping of the land using materials of various survey types, which enables carrying out the necessary actions on analytics, preliminary planning and design under office conditions. The object of the study is a rural area, the choice of which is due to the possibility of providing the general favorable environment in the region, as well as lack of attention to such territories and their “desolation”. The features of various types of software are analyzed; the way of their integration is described. A template for a database of objects of a three-dimensional map was developed. For mapping, the software designed for creating computer games is used, with its qualitative advantages of visualization and a considerable library of objects. The interface, tools, various features and capabilities of the used graphic editor are presented. An original mapping technique was developed; the stages of creating a 3D map are described and illustrated in detail. Further prospects of the work are outlined; its novelty and practical significance are noted.
