似大地水准面精化及其在重力勘探工作中的应用

Quasi-geoid Refinement and Its Application to the Gravity Exploration

通过精化似大地水准面在一个重力勘探工区中的具体应用,阐述局部似大地水准面的精化(使当地参考椭球面紧贴似大地水准面)过程、方法及其趋势改正在每个重力勘探点中的应用方法,在不考虑起算点误差的情况下使拟合精度优于5 cm,测绘成果更精准地服务于重力勘探工作,达到找矿的目的。

According to a specific application of refined quasi-geoid in gravity exploration work area,the authors describe quasi-geoid refined（the local reference ellipsoid closely Quasi-geoid）process,method and the trend correction in the application of gravity exploration point.Without regarding to the starting point of the error,the fit accuracy is better than 5 cm.More accurate surveying and mapping results serving the gravity exploration are to achieve the purpose of prospecting.
