The article solves an actual scientific and applied task, which is to form a methodological basis for the use of orthotransformed satellite imagery to create information services for environmental monitoring of objects of critical infrastructure. These services are designed to expand the capacity of the National Center for providing the information to central executive authorities about the results of environmental monitoring. The expansion involves the development of methods of using orthotransformed satellite imagery for the assessment of the environmental state. Based on the classification algorithm of enterprises and objects, a database of objects of critical infrastructure of Ukraine classified by their impact on the environment has been developed for the application in GIS-compatible systems.
      In the formation of the ideology of geographic information systems, the requirements for technical means are justified. These requirements include the deployed service, maintenance, filling and updating of the base of objects of critical infrastructure of Ukraine, the mechanism and order of visualization of impact assessments of all objects of the developed database. The algorithm has been adapted for application in an automated mode as part of GIS-systems.
      For research, the structure of the classifier using the state OCI register and validation of the developed methodology using the results of space imagery with specific examples for each of the objects of critical infrastructure of Ukraine has been developed. The following object is selected: Darnytsya Power Plant — an enterprise for the production and supply of electric and thermal energy. The study confirmed the relevance, scientific and practical value of using remote sensing methods for studying the ecological status of large areas of the earth’s surface.
