Abstract：With the rapid development of modern information and space technology, the digitization of regional geological survey has become an inevitable trend, which can achieve better information sharing and data update for geological work. The analysis on the architecture model of digital geological map spatial database, space storage, property inheritance, auxiliary tools for database building and quality monitoring is proposed, which offers technical guarantees for the building of spatial database and accuracy of data and improves the efficiency of spatial database building as well.
