Geoid determination in central Spain from gravity and height data

Gil, A. J. / Sevilla, M. J. / Rodríguez-Caderot, G.

Summary 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°× 1° blocks and predictions have been done in each block with gravity data spacing about 5′ × 5′ within each block, extended 1/2°. Topographic effects have been calculated from 6″ × 9″ heights using an RTM reduction with a reference terrain model of 30′ × 30′ mean heights.
