Abstract:
Abstract：The spatial database of 1：1M geological map of China has just been established in China, which includes ?2.0G abundant data of 64 geographical maps and 64 geological maps. The management system for this database has been designed on the basis of the MapGIS format, which integrates for the first time spatial database of 1：1M geological map with strata database. This management system is characterized by simplicity, flexibility, convenience and practicability. The major functions of the management system include the search of spatial scope, the retrieval of geographical and geological features, the display of various properties, the automatic creation of legends, and the inquiry of metadata. Using this new database management system, we can easily set up an operation platform for visualization of database applications, on which various visual figures, dynamic cartographies and special maps will be quickly created.
