|
摘要
采用EGM2008重力场模型和趋势面拟合与基于正交最小二乘思想筛选节点的多面函数法,运用移去恢复原理建立了太原市区的似大地水准面模型,拟合得到的模型内符合与外符合中误差均小于2 cm,完全可以满足太原市区内常规测量的要求。
A quasi- geoid model in Taiyuan urban areas established by using remove- restore method based on EGM2008 gravity field model,trend surface fitting and multi-surface function which choosing nodes by using the orthogonal least squares. The result shows that root mean square error of internal and external quality evaluation are both less than 2 cm,completely meet the conventional surveying production demand in the urban area of Taiyuan.
