摘要
当前GPS高程转换的方法较多,在进行转换时要根据现场情况选择不同的高程转换方法,本文通过采用不同的GPS高程拟合方法对实际测量数据进行计算、分析,验证了在小区域地势平坦的地区用GPS高程经转换后是否可以替代水准测量的可行性。
There are many methods for the current GPS Altitude Conversion,according to the different situation to choose Altitude Conversion method in the conversion,by using the method of GPS elevation fitting to different actual measurement data are calculated and analyzed to verify the feasibility,in a small area of flat area with GPS by Altitude Conversion after the conversion can substitute leveling.
