摘要
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.
