区域重力地改“测点高程平移法”精度探讨

DISCUSSION ON THE PRECISION OF SURVEY POINT ELEVATION LEVEL-MOVING METHOD IN THE REGIONAL GRAVITY TOPOGRAPHY CORRECTION

在讨论测点高程平移法区域重力地改的精度问题基础上,提出了系统差概念,并推荐一种新的计算方法,即把测点高程平移法和节点高程插值法有机地结合起来实现地改,通过理论模型和实例计算,表明该方法计算精度优于节点高程插值法和测点高程平移法。

Based on discussing the precision of survey point level -moving method in regional gravity topography correction, the authors put forward the concept of systematic error, and recommend a new calculation method correcting the topography by means of the survey point elevation level-moving organically combined with joint elevation insertion value method. The Computation of the theory model and the practical experience proved that the method is superior to joint elevation insertion value method and survey point elevation level moving one.
