摘　　要：根据GPS高程测量的相关理论,结合城市规划GPS高程测量的实际应用,以数值拟合为主,对高程拟合进行转换。用Matlab软件编写了相关的转换程序,根据实际相关工程验证,在不加地形改正的平原或丘陵地区,拟合出的正常高高程能够满足大比例尺测图和一般城市规划测绘工程精度要求,提高了工作效率并且降低了工程生产成本。According to the relevant theories of GPS height measurement and the practical application of GPS height measurement in urban planning, this paper focuses on numerical fitting and converts the height fitting. The GPS elevation control conversion program is compiled with Matlab software. According to the verification of actual related projects, in plain or hilly areas, without terrain correction, fitting the normal high-elevation to meet the general engineering and large-scale mapping accuracy requirements, which has reduced the cost of production to a certain extent.
