摘要
海洋区域地质调查需要信息准确、精度高的地理地图作为工作部署和成果图件编制的工作底图。海洋区域地质调查工作缺少可直接依据的地形图,需要综合编制涵盖陆地和海域的海陆一体化的地理底图,以更好地满足海洋区域地质调查的工作需要。以1:25万锦西幅和营口幅海洋区域地质调查为例,探讨了海陆一体化地理底图的编制过程和技术要点,并应用MapGIS软件编制了相应地理底图。
Marine geological survey requires high precision geographic base map as working map forwork planning and map compilation.Due to the differences in working techniques,methods and working areas between the marine geological survey and the survey on land,in particular for the area covering both the sea and land,regional geological survey needs a specific geographic base map to better meet the needs in regional geological survey.Taking the 1：250 000 marine regional geological survey in the Jinxi sheet and Yingkou sheet as cases,this paper discussed the compilation process of the geographic base maps with emphasis on some key technical points and the application of MAPGIS software.
