A MARINE AEROMAGNETIC DATABASE FOR EFFICIENT DATA MANAGEMENT

Following the principle of "integrated management of the sea and land", we designed in this paper an airborne gravity database table structure to make a unified airborne geophysical database, which includes airborne magnetic data, airborne magnetic gradient data, airborne electromagnetic data and airborne gamma energy spectrum data. On the GeoProbe platform, we developed a software for data services by using plug-in technology and WebGIS technology. Then we integrated the data service software, the data acquisition software and the airborne geophysical remote sensing data directory service system, and finally established an incorporate airborne geophysical data management service system. Adopting standardized data sorting process and strict data quality inspection measures, we put the airborne gravity data from the Bohai sea, Yellow sea and other sea areas into the database, about 3.5 square kilometers of ocean airborne gravity data was stored in the database. As the result, a marine geophysical database covering an area of about 4.97 million square kilometers of the Bohai sea, the Yellow Sea, the East China Sea, and the South China Sea has been constructed. The database may provide a series of service products of the whole sea area for users.
