DEVELOPMENT OF A WEB APPLICATION FOR SUSTAINABLE MANAGEMENT OF LAND AND WATER RESOURCES IN THE TERRITORY OF THE FORMER SEMIPALATINSK TEST SITE LOCATED IN AREAS PLANNED FOR ECONOMIC USE

The article presents the results of developing a web application for sustainable management of land and water resources in the territory of the former Semipalatinsk Test Site (STS), located in areas planned for economic use. The study describes the process of creating a spatial database using PostGIS, implementing server-side logic in Django, and visualizing geospatial objects with Leaflet.js. The developed application provides tools for displaying, filtering, and editing radiation and environmental data, including soil and water sampling points, geological structures, and infrastructure elements. The paper outlines the stages of developing a REST API (Representational State Transfer Application Programming Interface), mechanisms for importing data in CSV (Comma-Separated Values) format, and tools for interactive layer management on the map. The system is designed to support decision-making in the field of radiation safety and environmental planning.
