Abstract
For the Iberian Peninsula (-10.5<λ,<5.5, 35<φ<45) a quasigeoid solution has been computed using a global geopotential model, a digital terrain model and point gravity anomalies. The Fast Hartley Transform (FHT) technique has been used in the computations. The effect of topographic masses is taken into account by a residual terrain model (RTM) reduction using a 1000×1000 m DTM in the area. The region was divided into two sub-areas with a common part. Some experiments were performed in order to test the results obtained in each individual sub-area and also in a global calculation for all of the region. Then one solution was calculated at 80692 points in a regular grid covering the region and referred to the GRS80. Results are presented in a contour map.
