The observation points were installed on the main section and the three-dimensional coordinates of the points were measured by using the method of dynamic differential GPS. Meanwhile, the radar images of this subsidence area were processed by using the method of interferometry with daris software, and the interferogram of the subsidence area was obtained. Through this study, the GPS monitoring data and the InSAR deformation data were integrated and the dynamic subsidence contours of the experimental area were obtained. GPS/InSAR fusion technology provides a new technological means for large-scale dynamic monitoring of coal mining subsidence in western mountainous mining areas and shows good application prospects in coal mining subsidence monitoring and disaster warning.展开更多

Therefore, in order to improve the technical level of geological surveying and mapping and obtain richer and more accurate surveying and mapping results more efficiently, the application of GPS technology in geological engineering surveying and mapping work needs to be strengthened urgently. Based on the application principle of GPS technology, this paper comprehensively analyzes and summarizes the application advantages of current GPS technology and the application scope of GPS in surveying and mapping work, hoping to provide some reference for surveying and mapping work.展开更多
