Abstract: The article is devoted to the development of a software product for the approximation of digital terrain models for the purposes of environmental monitoring of chemically hazardous facilities. The article analyzes the current situation in the field of environmental monitoring of chemically hazardous facilities, identifies a problematic issue, which is the need to improve the efficiency of environmental monitoring systems using tools for modeling the migration of pollutants. Modeling of the migration of pollutants is carried out on digital models of the terrain of the territory, which creates certain difficulties in the form of a high degree of detail, which leads to the appearance of small areas of local accumulation of pollutants in the territory, which, due to the size of the territory under consideration, can be neglected. Thus, before using digital terrain models to simulate the migration of pollutants, their primary processing becomes mandatory in order to eliminate minor elevation differences and distortion of modeling results. To solve the identified problematic issue, a software product developed by the authors is proposed, aimed at approximating digital terrain models. The authors consider various approaches, methods and methods of performing approximation, identify the most promising from the point of view of the issue under consideration, and consider the need to develop additional modules and algorithms to improve the accuracy and clarity of the output data. The article provides a detailed description of the work of the software product as a whole and individual modules, provides algorithms and results (output data) of their work, and describes the graphical interface. During the analysis of the results of the software product, its high efficiency was revealed as part of the task of approximating digital terrain models, and conclusions were drawn about the possibility of its use in modeling the migration of pollutants during the improvement of the environmental monitoring system for chemically hazardous facilities .
