Abstract

Abstract

The People's Republic of China 1:2500000 digital geologic map space database was completed in 2001, after a two-year project. In addition to the main database, the database is composed of a geo-map database and geographic content attribute library, geologic content attribute library, color library, linear library, pattern library, symbol library and legend library. It includes the geologic content, administrative areas, arbitrary space and geographical content of the search and automatic output mapping, automatic drawing of geologic symbols, automatic legend and other functions. Database content includes:the People's Republic of China 1:2500000 vector geologic map 1, consisting of 0.7 GB of data. The 1:2500000 scale digital geologic map of the spatial database makes up for the gaps in the field. It is of great significance to show and improve the degree of geologic research in mainland China, to summarize and reflect the overall characteristics of China's geology, and to provide basic geologic data for economic construction, land and resources management, geologic survey and so on.
