基于区域似大地水准面及DEM的佛山市2000坐标系建立方案优选

The Optimization of Foshan City 2000 Coordinate System Establishment Based on the Regional Quasi-geoid and DEM

根据国家相关技术要求,以佛山市为例,介绍了利用区域似大地水准面及DEM成果建立基于CGCS2000的新一代城市相对独立坐标系的优选方法,通过几种方案的比较分析,得出适合佛山市实际情况的坐标系建立方案,对其他城市开展同类工作提供借鉴。

According to the relevant technical requirements of the state,in this paper,taking Foshan as an example,an optimization method is introduced for establishing a relatively independent coordinate system based on CGCS2000,which used the regional quasi-geoid surface and DEM results.On basis of the comparative analysis of several schemes,the coordinate system has been put forward to account for the actual situation of Foshan City.Meanwhile it might be applied to similar work in other cities.
