For their application it is neccessary to have already achieved subdecimeter or even better " cm " -model of the geoid surface , spreading through Slovenia to Austria , in order to enable the transformation from ellipsoid into the in the praxis indisepnsable orthometric heights ( altitudes ) . Regional and local highly distinguishable geoid model , as physically defined reference surfaces , are necessary in all geosciences ( geodesy , geophysics , oceanography ) , in numerous projects , e. g. for using the altimetric measurements from the Satellite ERS-1 .
