摘要:
提要:全国1∶50万地质图数据库以国产软件MAPGIS作为基础平台,以各省(区)区域地质志附图和香港特别行政区1∶20万地质图为基础资料,采用现代地质学、地层学、岩石学等的新理论和新的表示方法,按岩石地层单位、花岗岩谱系单位,侵入岩按时代加岩性编制而成。该库由数字地质图库和地理底图库构成,可按任意空间范围、不同比例尺、不同投影方式和不同地质、地理内容等单项或多项任意检索;通过检索能自动形成具有图例、图外整饰的完整的地质图。

Abstract:
Abstract: The 1:500000 geological map database of China was developed with the China-made software MAPGIS 5.0 as the basic platform and the appended maps (1:500000) of regional geology of all the provinces, autonomous regions and municipalities and the 1:200000 geological map of the Hong Kong Special Administrative Region as the basic data. The geological map was compiled by using new theories and ideas on modern geology, stratigraphy and petrology and new methods of presentation and according to the lithostratigraphic units, hierarchical units of granites and time plus lithology for intrusive rocks. The database was composed of the digital geological map database and geographic base map database. The retrieval can be made arbitrarily according to any space scope, different scales, different projection methods and different geological and geographic content, and one can retrieve one item or multiple items. Through retrieval a complete geological map with the legend and ornaments is produced automatically.
