| Abstract: | Combined with the application of GPS control net in a large-scale water conservancy project in Guangxi,introduction and analysis was made on the elevation conversion method of transforming GPS ellipsoidal height into normal height.The Guangxi quasi-geoid refining results were applied in GPS elevation conversion.The results of accuracy analysis demonstrate that this method improves the accuracy and efficient of elevation survey. |
| Keywords: | WGS-84 coordinate system GPS ellipsoidal height normal height elevation conversion |
