The subject of this thesis is comparation methods of measuring elevation of experimental points on the network site Tetčice. There was mutually comparated height differences , which were mesured with methods of precise leveling, trigonometric method and fast static GPS measurment method. It was experimentaly used Sanchez method to reduce the effects of refraction measured at zenith angles. In the area of interest was used the method of interpolation to height calculation of point Bučín in elevation system Bpv, calculated from quasi-geoid heights on the surrounding leveling points.
