三角平面拟合法在重力地形改正中的应用

摘要

介绍了三角平面拟合法在重力勘查近中区地形改正中的应用.该方法应用三角平面拟合通过地形图DEM模型数据(或散点模型数据)直接内插求得地形改正量板模型的结点高程数据,实现了地形改正的电脑化作业.%The application of the triangular plane fitting method to gravity terrain correction is described in this paper. By interpolating DEM model data( or powdery point model data) of topographic map and using the triangular plane fitting method, node elevation data of terrain correction measuring board model can be obtained, with which the computerized operation is realized in terrain correction.
