中华人民共和国1:250万数字地质图空间数据库

People's Republic of China 1: 2.5 million digital geological map space database, in 2000 project, completed in 2001, which lasted two years. In addition to the main database, the database is composed of geo-map database and geographic content attribute library, geological content attribute library, color library, linear library, pattern library, symbol library and legend library. With the geological content, administrative area, arbitrary space and geographical content of the search and automatic output mapping, automatic drawing of geological symbols, automatic legend and other functions.1: 2.5 million scale digital geological map of the completion of the spatial database to make up for the gaps in the field. It is of great significance to show and improve the degree of geological research in mainland China, to summarize and reflect the overall characteristics of China's geology, and to provide basic geological data for economic construction, land and resources management, geological survey and so on.

中华人民共和国1:250万数字地质图空间数据库为2000年度立项项目，于2001年竣工，建设工期共计两年。该系统除主数据库外，还由地理底图数据库、地理内容属性库、地质内容属性库、色库、线型库、花纹库、符号库及图例库共同构成。其具备地质要素、行政区划、任意空间范围与地理内容的检索能力，可实现自动成图输出、地质符号自动绘制及图例自动生成等功能。该1:250万比例尺数字地质图空间数据库的建成，填补了国内相关领域的空白。其对于展示并提升中国大陆地区的地质研究程度、系统总结与反映我国地质整体特征，以及为经济建设、国土资源管理、地质调查等工作提供基础地质数据均具有重要意义。
