摘要
针对分区拟合转换成正常高的方法中,对分区进行拼接时存在的一些问题,采用广义延拓法对面积较大或地形变化比较复杂的区域进行GPS高程转换。实测算例表明:该方法能提高大面积区域GPS高程转换的精度和避免分区间的台阶性突变。
For solving the problems in the sub-regional riging up of the sub-regional fitting and transforming GPS height into normal height, this paper uses the generalized extension interpolation method in the large or complex area of to pographic change in GPS height conversion. Practical examples show that, by use of this method, the accuracy of GPS height conversion can be improved and the sudden step change can be avoided as well.
