The features of database design in thematic and satin mapping are considered. The requirements for databases of special and thematic maps were determined, taking into account the process of geocoding objects, classification and coding of thematic objects, and the structure of tables. The main blocks of information allocated in thematic databases are given. It was proposed to add to the database an additional block designed to store information about the topological interconnection of thematic objects with general geographical elements of the map's content and providing automation of the process of selecting thematic objects and coordinating them with the image of settlements, roads and rivers. The required fields are defined and examples of the structure of thematic database tables for atlas mapping are given.
