Geoid determination in central Spain from gravity and height data

Abstract

The least-squares collocation method has been used for the computation of a geoid solution in central Spain, combining a geopotential model complete to degree and order 360, gravity anomalies and topographic information. The area has been divided in two 1-degrees x 1-degrees blocks and predictions have been done in each block with gravity data spacing about 5' x 5' within each block, extended 1/2-degrees. Topographic effects have been calculated from 6'' x 9'' heights using an RTM reduction with a reference terrain model of 30' x 30' mean heights.
