摘要
介绍了一种GPS高程拟合的新方法,即首先通过采集测区已有的高程点或水准点资料,进而求出这些点的高程异常值,接着构建高程异常的TIN模型,然后通过移动三角面进行高程异常值的拟合处理,最后求出GPS点的正常高程值。实验证明,该方法能够较好地改善GPS高程的拟合精度。
This paper introduces a kind of new method of height fitting, first, collecting data which are known height points or leveling points, and then solving out height anomaly of above mentioned points, in the train of structuring TIN model of height anomaly, at last the height anomaly value of all points are processed through mobile triangle surfaces.
