Precision Analysis of EGM2008 Solving Height Anomaly in Xinjiang Area
Abstract Based on the analysis of 998 groups of leveling data in 38 survey fields, distributed in 13 administrative divisions throughout Xinjiang, we come to the conclusion that the overall precision EGM2008 in Xinjiang is 0.146 m. We summarize the distribution regularities of height anomaly precision and changes varying with distance of EGM 2008, and propose that, within a certain scope, the EGM 2008 transformation results of GPS ellipsoidal height can replace fourth and lower grade leveling.
Key words :
