中华人民共和国1：250万数字地质图空间数据库经过两年的建设，于2001年建成。该数据库除主数据库外，还包括地理地图数据库和地理内容属性库、地质内容属性库、颜色库、线性库、图案库、符号库和图例库。它包括对地质内容、行政区域、任意空间和地理内容的搜索和自动输出制图、自动绘制地质符号、自动图例等功能。数据库内容包括：中华人民共和国1：250万矢量地质图1幅，由0.7 GB数据组成。1：250万数字地质图的空间数据库弥补了该领域的空白。对于展示和提高中国大陆地质研究的程度，总结和反映中国地质的总体特征，为经济建设、国土资源管理、地质调查等提供基础地质资料，具有重要意义。
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.
