Resumo: The development of the Earth Gravitational Model 2008 (EGM2008) model is asignificant contribution for modeling the Earth’s gravity and geoid. Recently, it canbe confidently used versus geometric models following a simple refinementprocedure. Several studies show that, EGM2008 can reach the accuracy of regionalor local geoid models after modeling the differences between the GPS-levelinggeoid heights and EGM2008 derived geoid heights at identified control points. Thestudy focuses on a corrector surface fitting (CSF) approach based on radial basisfunctions (RBF) as improvement procedure for EGM2008. A detailed mathematicalmodel and solution algorithm of the proposed model is given, and it has beenapplied in different test areas covering the city borders of Bursa, Konya, Denizli andGaziantep in Turkey. Accuracy of the improved model was evaluated in scatteredcheck points within test regions. The geoid heights of all check points obtained byGPS-leveling measurements were compared with the geoid heights obtained fromimproved model. The discrepancies between the calculated and measured geoidheights were analyzed and discussed.
