Abstract

V diplomski nalogi smo se osredotočili na oceno višinske točnosti lidarskega DMR1, izdelanega v projektu Laserskega skeniranja Slovenije (LSS). Primerjamo višine točk, dobljene z GNSS-višinomerstvom in iz DMR1. Izmera je potekala pod nadvozom Dolgi most v Ljubljani. Prvi del naloge se nanaša na teoretični opis lidarja, projekta LSS in izmere GNSS. V drugem delu opisujemo praktično delo s potekom terenskega dela in določitve koordinat s kombinacijo terestrične in GNSS-izmere. Višinsko točnost DMR1 ocenimo z višinskimi razlikami med točkami, izmerjenimi na terenu, in interpoliranimi točkami iz DMR1. Rezultati analize so pokazali, da je DMR1 pod nadvozom Dolgi most ustrezne višinske točnosti.

Secondary title: GNNS measurements for vertical accuracy assessment of the digital terrain model under the crossover Dolgi most
Secondary abstract: The thesis aim is to compare data from various sources in order to check the elevation accuracy of the DMR1 produced in the Laser Scanning of Slovenia (LSS). We compared elevations of points, acquired with geodetic GNSS as well as terrestrial positioning and from DMR1. Measurements were performed under the bridge Dolgi most in Ljubljana. The first part consists of the theoretical framework about Lidar, LSS project and description of GNSS. The second part of the thesis is practical describes the fieldwork and determination of the coordinates by combining GNSS-RTK and terrestrial positioning. The elevation accuracy of the DMR1 is estimated based on the elevation differences between the points measured on the fieldwork and the interpolated points from DMR1. The conclusion of the thesis includes main findings, that DMR1 under the bridge Dolgi most is of an appropriate elevation accuracy.
