Zaměření železničního bodového pole a 3D osy koleje traťového úseku Boří les - Valtice

Abstract

This thesis describes the measurement of the railway geodetic point and 3D rails axis on track section 2081 Boří les - Valtice on the track Břeclav - Znojmo. The thesis is divided into the theoretical and practical part. The theoretical part describes all the methods used in the measurement, among these methods are GNSS technology, two-sided connected and oriented polygon program and geometric leveling. There is also explained the layout of the points of the primary and secondary system of the railway point field. The practical part describes the reconnaissance of the terrain, the instrumentation used in the measurement of the positional and altitude field, the realization of the measurement, the processing of the measured data in the computational programs and the final evaluation. At the end of the practical part, the focus and calculation of the 3D axis of the track are described.
