Abstract

This baccalaureate thesis compares altitudinal measuring methods GNSS and diferential leveling. In the first part of work basics of diferential levelling are described, primarily when the leveling instrument is positioned midway. It describes precise leveling, errors in leveling and introduces equipement for this measuring method of elevation. Following part of thesis describes principles of GNSS method, phase measurement, dual-frequency receivers, used device and GNSS equipment. The thesis is as well as focused on describing of measurement process with its elaboration and outcome interpretation of both used methods. Last part of thesis contains evaluation of results, comparison of both used methods, thein advantages and disadvantages.
