Abstract Through the analysis of the forced Earth’s surface and quasigeoid’ we found out that the traditional method for calculating the terrain correction may make errors.We explained the reasons for the formation of the error,derivated the formula, analyzed the source and size of its errors,and then put forward a new algorithm for calculation of terrain correcting.
Key words ：
terrain correction
geoid
