CHOICE AND ACCURACY ANALYSIS OF OPTIMAL EARTH GRAVITY
FIELD MODEL IN GUANGDONG REGION
Surveying and Mapping Institute Lands and Resource Department of Guangdong Province, Guangzhou 510500
Abstract Several earth gravitational field models are compared and analyzed based on the GPS/leveling data, which are distributed over not only Guangdong region but also densely over two local areas. The result shows that the accuracy of the EGM2008/ EIGEN6C（1420） model is the highest with 0.066 m in Guangdong region.
Key words ：
