摘要
简要介绍了区域似大地水准面模型的精化方法,通过基础框架网及高精度水准网的布设,利用高阶地球重力场模型EGM2008、高精度GPS、水准数据及高分辨率数字地形模型(DTM)建立了湛江市辖区分辨率为2 km×2km格网的似大地水准面模型。
The method of local quasi-geoid determination was briefly introduced in this paper.Base on the layout of basic control network and high precision leveling network,a local quasi-geoid model in Zhanjiang city areas with 2 km grids was constructed by high-precision GPS,leveling data,high-resolution DTM and high degree earth gravity field model EGM2008.
