Abstract:

Using Earth Gravitational Models and computation of the additional local terrain corrections to geoid undulations (or height anomaly) is a method for improvement of the GPS levelling accuracy. The relations between topographic surface and geoid undulation of the earth gravitational models DMA10, OSU91A, EGM96, EGM2008 are useful information for determination of local terrain corrections.
