The Refined Gravity Field Models for Height System Unification in China

The Refined Gravity Field Models for Height System Unification in China

A unified height datum is essential for global geographic information resource construction, ecological environment protection, and scientific research. The goal of this paper is to derive the geopotential value for the Chinese height datum (CNHD) in order to realize the height datum unification in...
