摘　　要：利用GPS定位的原始高程,通过二次曲面拟合,将大地高转化为正常高,将转换后的GPS高程和水准高程比较,表明GPS高程可以满足一定精度的测绘工程需要。Using GPS positioning original height, GPS geodetic height can be transformed into normal height by conicoid fitting. Through comparison between GPS height after transformed and leveling height, GPS height after transformed can need certain precision requirement of surveying and mapping engineering.
