Abstract:In order to meet the needs of geological information for economic development and national defense construction in national terrestrial and marine border region, Aero Geophysical Survey & Remote Sensing Center for Land and Resources (AGRS) has carried out geological remote sensing survey with 24 other institutions since 2011, including regional geological survey centers, institutes of geological survey, universities and other research institutions. The project group obtained the geological data of 950 thousand km2 in the northeast, northwest and southwest terrestrial border and the Sansha of South China Sea. And these geological data mainly included nine kinds of information, such as fundamental geology, engineering geology, hydrogeology, mineral geology, geological hazard and so on. It has also completed 32 kinds of 1:50 000 and 1:250 000 thematic application maps which can be used in economic development and national defense construction. So the technical system of geological remote sensing survey in terrestrial and marine border region, the sharing database and the application achievements have been completed to solve the difficulty of geological survey in terrestrial and marine border region and to innovate the model of geological survey of Military-Civil Integration. Based on the main purpose of geological remote sensing survey in national terrestrial and marine border region, the paper summarized the technical route and achievements, and looked ahead to the future work.
