| Abstract: | Based on the GPS surveying and leveling materials, two weight functions of moving surface model which are applied to the GPS height data conversion in the mountain areas are mainly studied. And the fitting precision is analyzed and compared. From the results, it can be found that applying the radial weight functions to moving surface model have an effect on the GPS height conversion in the mountain areas. |
