The area covered by this geoid estimate is 35 ° < lat < 44° , -10° < lon < 4° with grid spacing of 1.5' x 1.5'. The computation is based on the remove-restore technique, using the high resolution digital terrain model SRTM90m for the topographic reduction and the new EIGEN-CG01C geopotential model. The solution has been obtained in one step only over the whole area using the FFT estimation method.
