| Abstract: | The article discusses how to derive the high geoid in the method of gravity(Stokes formula and,Molodensky theory) and GPS leveling,puts forward the thinking of determining GPS spots' leveling and geoid by the model.The local geoid have been examined.The examination results demonstrate that the accuracy of the geoid is reliable.At the same time,a functional software is presented,and the local geoid has been applied in surveying and mapping.The advantages of GPS surveying,such as convenience,better precision,higher efficiency,lower cost and so on,will be utilized in surveying and mapping. |
| Keywords: | geoid GPS leveling gravity |
