Development of information system for storing and processing the results of agricultural land monitoring in the south of the Far East

Digitalization of agriculture is one of the strategic directions of economic development. To store and process the results of satellite monitoring of agricultural lands, it is planned to develop information systems (IS) at the federal and regional levels. The article discusses the issues of developing an appropriate IS for the southern part of the Far East. A two-level system including client and server levels is described. The implemented database (DB) management system based on PostgreSQL with the PostGIS extension has a cluster structure where the subject of the Russian Federation is considered as a cluster. The cluster is logically divided into 5 main modules which are grouped tables with data of different types. Triggers and trigger functions are used to optimize the operation of the IS and the possibility of sharing DB is also provided. The DB is being tested and filled for the Khabarovsk and the Amur Regions.
