The Libya gravimetric geoid was computed by using Stokes' integral in the framework of a remove-restore technique. The integral is evaluated in the frequency domain by the multi-band Fast Fourier Transform approximation with a proper zero padding. The used data were: 5' x 5' gridded value of Bouguer anomalies (onshore) and free-air anomalies (offshore) released for geoid computation by GETECH, a 5' x 5' global digital terrain model, the OSU91A and EGM96 global geopotential models.
