Abstract
Through the establishment of feature-level multi temporal National 1:50 000 Topographic Database, the management of feature-level topographic data and the storage of multi temporal information is realized. This paper describes the technical design of building database and management for feature-level multi temporal topographic database, and shows the application of the Database management service system.
