The spatial information integration research of gravity and magnetic regional field based on GIS
基于GIS的区域重磁空间信息集成研究

According to the characteristics of gravity and magnetic regional field, the gravity and magntic data can be processed and drawn automatically on the computer with the theory, which includes concluding linear structure of the anomaly body by using the horizontal first derivative and ring structure of the anomaly body by using the vertical second derivative. Then, graphs are identified with the pattern based on the spatial analysis of GIS. The automatic extracting the gravity and magntic structure and integrating the spatial information has been realized in a region. It has been used in interpreting 1:1,000,000 gravity data in the east of KunLun, China. The result shows that it is the utility. The technology of information integration can be used to change the old working mode, which explains data by hand using transparent papers overlay.
