I am presently working on local geoid model determination using gravimetric-geometric method. To obtain the gravity anomalies of chosen points, the points absolute gravity and their respective theoretical gravity must be obtained. Someone should please help me, I want to know if it is ideal to compute the theoretical/latitude gravity on WGS84 ellipsoid or it must be computed on the local ellipsoid adopted for geodetic computation in the area of study.
Dear, Okiemute
The local geoid determination by gravimetric method required that :
Transform all data to a global geodetic datum (here, WGS84)

If you need to determine WGS 84 geoid then you shall compute the standard gravity (Latitude) on WGS84, otherwise for local geoids you have to use your local ellipsoid parameters
Wish you all the success
Thanks so much Associate Professor Kamal Sami for your response toward my question. I would adhere to what you said.
