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.
