Tvorba detailního modelu kvazigeoidu na severovýchodní Moravě a ve Slezsku

Abstract

Presented work deals with the evaluation of a detailed quasigeoid model of northeast of Moravia and Silesia and quasigeoid course verification using GNSS/levelling method. The introductory part deals with the classification of figures approximating the shape of the Earth, interrelations of their reference levells and theory of hights. The thesis further concentrates determining the heights of the Czech republic, where they are first given information about elevation fundamentals, terrain elevation model and campaigns for the implementation of the ETRS. At the end of the introductory section summarizes existing quasigeoid models and missions to discovery gravity field. The main part of the thesis is devoted to the design and realization of measurement to supplement maintenance of survey control points, requesting gravity anomalies and digital terrain model data. Next part treats with evaluation of the quasigeoid course with comparison with previous models. In the final part there is evaluated final rectified quasigeoid model which is compared with model CR2005 and GNSS/levelling.
