Abstract

V magistrski nalogi analiziramo višine točk iz podatkov klasične geodetske izmere, ultrazvočnega globinomera z eno in več sondami ter aerolaserskega skeniranja. Testno območje predstavlja deset prečnih profilov in betonski bloki na reki Dravi pred hidroelektrarno Mariborski otok. Analiza temelji na primerjavi rezultatov izračuna razlik višin med podatkovnimi seti vseh uporabljenih metod izmere. V nalogi so predstavljene glavne lastnosti uporabljenih tehnologij, instrumentarij, postopek pridobitve podatkov in numerični ter grafični prikazi rezultatov. V nalogi podrobno predstavimo rezultate primerjalnih analiz s statistično analizo. Ugotovili smo, da so razlike višin točk na betonskih blokih med klasično terestrično izmero in ultrazvočnim globinomerom z več sondami ter aerolaserskim skeniranjem minimalne. Iz analize primerjav višin na prečnih profilih struge reke Drave, dobimo občutnejše razlike, ko primerjamo podatke ultrazvočnega globinomera z eno sondo s podatki ultrazvočnega globinomera z več sondami ter aerolaserskega skeniranja.

Secondary title: Analysis of cross sections on the Drava River from data obtained with different measuring methods
Secondary abstract: In the master thesis we analyse the heights of points obtained from the data of classical geodetic terrestrial measurements, from single beam and multi beam sonars and from airborne laser scanning. The test area represents ten cross sections and concrete blocks on the Drava River front of the Mariborski otok hydropower plant. The analysis is based on a comparison of the results of the calculation of the height differences between the data sets of all measuring methods used. In the master thesis we present the main features of the technologies and instruments used, the data acquisition process and the numerical and graphical representations of the results. In the thesis, we also present the results of comparative analysis by statistical analysis. We found out that the height differences on concrete blocks between classic geodetic terrestrial measurements, single beam and multi beam sonar and airborne laser scanning are minimal. Nevertheless, we found significantly higher differences when comparing single beam data with multi beam and airborne laser scanning data when analysing cross sections on the Drava river.
