| Abstract: | Based on the geodetic coordinate calculation model and the quasi -geoid model, in view of the network RTK observation data, using Visual Basic 6 programming language tools to prepare a coordinate conversion process can quickly, accurately realize the 2000 national geodetic coordinate sys- tem and the calculation of normal high plane coordinates. This paper briefly introduces the principle of geodetic coordinates to the Gauss projection plane coordinates and the quasi - geoid model to calculate the normal height,analyzes the main program design process. A practical example of the effect of program transformation is analyzed. |
