基于WGS84正常重力公式的重力外部校正方法
Gravity external correction method based on WGS84 normal gravity formula
摘要
Abstract
Taking WGS84 ellipsoid as the datum to create a normal gravity fomula of the earth's surface, the normal gravity of every survey points in the earth surface can be directly computed by the formula and the gravity abnormal to the survey points' location could be calculated directly so that the problmes in gravity external correction can be avoided. The results of the observed gravity data show that compared with Bouguer gravity anomaly, the gravity anomaly eaculated by the formula could reflect information of structure much clearly, and some small faults and rocks could be found easily in the gravity anomaly.关键词
