摘要
区域范围内,将解算后的GPS观测值的大地高转换到日常生产生活中使用的正常高的过程中,多面函数转换法已经比较常用。对多面函数中心节点的选择,通常是人工选择均匀分布特征点,本文提出通过网格划分的方法,选取格网交叉点为多面函数中心节点的自动选择模型,并通过实例验证其可行性。
In the regional,the way of convert the geodetic height,that was solved,to the normal height by polyhedral function,was very commonly.To choose of polyhedral function＇s center node,it＇s very commonly,to select the feature points of uniform distribution,by manual work.This essay asked the measure of divide the grid,so that we can pick up the grid intersection,and this was an automatic process,finally this thought was improved.
