| Abstract: | The EGM2008 model is briefly introduced. The Trimble Total Control 2.73 Tempo software is used to load global 2.5 × 2.5 grid data of EGM2008 and applied to conduct GPS leveling for existing GPS and leveling data. Based on comparison of results of three different GPS leveling methods, some useful conclusions are obtained. |
