摘　　要：地质调查项目信息化建设是实现地质调查有效服务国家生态文明建设重大需求的支撑体系之一。数字填图技术是地质调查项目信息化建设中的关键技术,使得野外数据采集、数据处理、成果输出等全流程信息化得以实现。文章针对地质调查项目信息化建设过程中的技术难点,应用最新的数字填图系统平台,总结出一套简明实用的地质调查项目信息化建设方法:首先,优选符合地质调查精度要求的数据源,并采用2000国家大地坐标系;而后,运用数字填图技术系统中DGSGIS工具下载、配准所选取数据源影像作为地理底图;最后,使用数字填图系统建设完成地质调查项目空间数据库。该方法技术流程简洁、实用性强,对地质调查项目信息化建设具有一定指导意义。The informatization construction of geological survey project is one of the supporting systems to realize the effective service of geological survey to the national ecological civilization construction. Digital mapping technology is the key technology in the informationization construction of geological survey projects,which makes the whole process of field data acquisition,data processing and output of results informationized. In view of the technical difficulties in the informatization construction of geological survey projects,a set of concise and practical informatization construction methods for geological survey projects are summarized by applying the latest digital mapping system platform. Firstly,the data sources that meet the requirements of geological survey accuracy are selected,and the 2000 national geodetic coordinate system is adopted. Then,the selected data source images are downloaded and registered by DGSGIS tools in the digital mapping technology system as the geographic base maps.Finally,the spatial database of geological survey projects is constructed by using the digital mapping system. This method is simple and practical,and has certain guiding significance for the informatization construction of geological survey projects.
