宁波市似大地水准面数字高程基准建设及精度检验

摘要

Based on the 2000 national geodetic coordinate system and the 1985 National Vertical Datum, this paper described the method which organized the construction of Ningbo quasi-geoid digital vertical datum in NBCORS and Ningbo basic elevation control network 3D framework. At the same time, it conducted the accuracy test of correctness and practicality and the accuracy region's partition.%基于2000国家大地坐标系和1985国家高程基准,阐述了在NBCORS和宁波市基本高程控制网的三维框架下组织实施宁波市似大地水准面数字高程基准建设的方法,并进行了似大地水准面的正确性和实用性精度检验以及精度区域划分.
