YAN Zhi-gang, ZHANG Xing-fu (1.Survey Branch of the 1st Company L.td of the MBEC, Zhengzhou 450053,China 2.Department of surveying and geomatics,Tongji Universty, Shanghai 200092,China)  
Coordinate transformation and height interpolation are the main methods for GPS-RTK height surveying.This paper introduces the coordinate transformation and how to validate the results of GPS-RTK height surveying. The conventional method for validating height is the comparison the height of the connected leveling points and GPS-RTK points. A method for validating GPS-RTK height results based on coordinate transformation by means of line or plane height interpolation is given out in this paper.The results show this method is feasible.
