综合利用DEM数据、似大地水准面精化成果,可实现对独立坐标系拟建设区域高斯投影综合变形的精确定量、定性分析。汕尾市的应用案例表明,应用该方法建立区域独立坐标系具有实施的可行性和精度的可靠性,可为地方独立坐标系建立和应用提供科学的参考。

Comprehensive utilization of quasi-geoid model and DEM, can realize accurate qualitative and quantitative analysis of the comprehensive deformation of Gauss projection in the area to be constructed by the independent coordinate system. The application case of Shanwei City shows that using this method to establish the regional independent coordinate system has the feasibility of implementation and the reliability of accuracy, which can provide scientific reference for the establishment and application of independent coordinate system.
