| Abstract: | Based on comprehensive utilization of GPS and leveling information,aiming at GPS in a large survey area with complex topography,the authors put forward a new method for subregional fitting and transforming GPS height into normal height,analyzed the applicability of the fitting models,proposed the method of using bicubic splines or bicubic surface function to carry out the smoothing junction for two fitted subregions,and presented corresponding algorithms and accuracy evaluation standards. It is verified tha... |
