摘要: 根据地矿部“地矿工作信息化工程”总体部署，地调局设立了区调数字地质图系统的研究项目。其目的是通过试验研究解决１∶５万区调数字地质图的数据标准问题，制订统一的工作流程和技术要求，推广应用ＧＩＳ技术。重点论述了项目的目标、意义、研究内容、技术路线、图层划分、工作流程等方面的内容。Abstract: According to the overall plan of the information engineering of the Ministry of Geology and Mineral Resources （MGMR）, the Bureau of Geological Survey set up a project of the digital system for geological map production for regional surveys. Its purpose is to solve further the problem about the data and criteria for 1∶50 000 digital geological map production through experimental study so as to work out a unifying work process and technical requirements and spread the application of the GIS technique. This paper mainly deals with the objective, significance, research contents, technical line, map layer division and work process, which may be used for reference in the further study.
