Elipsoidal heights determined by GPS is different from orthometric heights used in surveying applications. Therefore, elipsoidal height determined by GPS is transformed to orthometric height. It can be used several transformation methods to do this transformation. In this study, we used five surface fitting techniques which are Inverse Distance Weighted (IDW), Polinomal Regression, Multiquadratic interpolation, Least square collocation and Universal Kriging (UK) and eighteen subvariations which are related to these techniques in three different test areas. We were studied relationship between obtained accuracy and surface fitting tecniques by analizing results obtained from three test areas.
Key Words: Interpolation; collocation; multiquadratic; kriging
