| Abstract: | RTKGPS surveying has been applied widely in China. Its results belong to the WGS-84 coordinate system. In practical application, the coordinate must be transformed from the WGS-84 coordinate system to the national coordinate system or the local independence coordinate system. So it is a key problem to solve the coordinate transformation parameters correctly in different coordinate system for the application of RTKGPS surveying. This paper provides several methods and their mathematic models for calculating coordinate transformation parameters in coordinate system transformation which are applied in RTKGPS surveying, and introduces several fitting methods in the transformation between geodetic heights and normal heights. |
