| Abstract: | The establishment of the Aeromagnetic Database of the Provincial Level is a project assigned by the Bureau of Geological Survey.In order to provide qualified data for the establishment of database,the Arogeophysical Survey and Remote-Sensing Center,aiming at utilizing large quantities of available aeromagnetic simulation data and based on test and summarization,has suggeted carrying out digitization on the aeromagnetic Δ T profile centimeter base map by means of digitization instrument and described its method,technological process and requirements for testing quality.The digitization of aeromagnetic simulation data obtained from 138 surveyed areas by Aerogeophysical Survey and Remote-Sensing Center has been completed,and the aerogeophysical data to be put in the database has been collected from most areas of China.In addition,this method has been recommended to various geological exploration units. |
