| 摘 要： | 在一般的地形测量中,GPS测量已成为获得点的平面坐标的最主要的方法。但是,GPS 3维坐标中测得的大地高未能在生产实际中发挥应有的作用。因此,需将GPS大地高转换成正常高。本文在实地的地形测量中,根据已有点的高程数据和联测的GPS高程数据,采用等值线图示法和平面拟合法对测区内进行GPS高程拟合,并对两种方法的拟合精度进行比较。最终认为在平坦地区等值线图示法要比平面拟合法更好些。

| Abstract: | GPS measurements have become the most important method to obtain the coordinates of points in the measurement of the terrain. But the geodetic height obtained from GPS cant play its role, so the GPS geodetic height needs to be converted into normal height. We use the two commonly used methods to fit the GPS elevation based on the actual measured data, and then compare the ac- curacy of both methods. We conclude the most appropriate elevation fitting method in the local region. |
