Abstract: We try to summarize the techniques used for digital map compilation for the marine territory of China in this paper. The new version of 1:1000000 geological and geophysical map series of China Seas and Adjacent Regions include five maps, i.e. the Bouguer gravity anomaly map, spatial gravity anomaly map, magnetic anomaly map, surface sediment distribution map and regional geotectonic map. The mapping area also covers part of the land and adjacent areas in addition to China seas. The geological and geophysical maps have not been renewed since the last map series published 20 years ago. And the maps published then were drawn by hands. Either precision or quality is not able to meet the demand of users. This time, we compile maps with MapGIS as a platform. Various equipments, such as computers, advanced digitizers and other facilities, are adopted for the map compilation. At first, we, using digital map compilation technology, standardized and unified all the data, including both the old and new data, and the data collected with different methods and from different channels. Rationale fitting technique and reliable coordinates transform are used to guarantee the quality of the maps. In the process of map compilation, a GIS database has been constructed. All the maps, including the base map and specific maps, were drawn on the MapGIS platform using point, line and polygons as legends and layers were designed and constructed according to the data available and the contents the maps need. The use of the MapGIS platform made us possible to ensure the precision of the maps and enhance the efficiency of map compilation. It is believed that the compilation and publication of the new version of 1:1 000 000 Geological and Geophysical Map Series of China Seas and Adjacent Regions will certainly help the readers better understand the basic geological regulations of China.
