Abstract
V diplomski nalogi primerjamo podatke iz baze DTK 5 s podatki terenske izmere z GNSS na izbranem območju gozdnih cest Šišenskega hriba. Ker terenska izmera z GNSS omogoča določitev 3D-položajev točk, smo vzporedno naredili tudi primerjavo višin tako, da smo interpolirane višine iz DMV 5 primerjali z višinami, pridobljenimi z GNSS-terensko izmero. Izmero smo izvajali v dokaj neugodnih razmerah za GNSS in ob tem primerjali zmožnost določitve položajev točk z instrumentoma Leica Viva GS15 in Javad Triumph-LS. Medtem, ko smo z instrumentom Javad Triumph-LS v času še nepopolne zazelenitve listnatega gozda lahko tudi v oteženih pogojih uspešno določili položaje množici točk, smo bili ob uporabi instrumenta Leica Viva GS15 manj uspešni, zato smo točkam položaje določili s kombinacijo klasičnih in GNSS meritev. Na danem testnem območju smo ugotovili, da so odstopanja v horizontalni ravnini glede na DTK 5 in višinska odstopanja glede na DMV 5 večja na območjih z visoko vegetacijo. Položajne razlike na območjih brez vegetacije so bile precej manj očitne.

Title:DTK 5 and DMV 5 data comparison according to the positions from combined GNSS and classical geodetic measurements at the area of forest roads
Abstract:
In the following diploma thesis, we compared the data from the database DTK 5 with the data from field measurement by GNSS in a selected area of forest roads of Šišenski Hill. Since the terrain measured by GNSS enables the determination of the 3D position of points, we also made a parallel comparison of heights, so that we were able to compare the interpolated heights measured by DMV 5 with the heights obtained from GNSS field measurement. The measurement was carried out in rather unfavourable conditions for GNSS and during the measurements we also compared the ability to determine positions of points with the instruments Leica Viva GS15 and Javad Triumph-LS. Despite difficult conditions, at the time of still incomplete greening of deciduous forest, we were successful at determining the position of plurality of points with usage of instrument Javad Triumph-LS. With the usage of instrument Leica Viva GS15 we were less successful. Therefore, we determined the points’ positions with a combination of GNSS and classical geodetic measurements. At the given test area, we discovered that the deviations in the horizontal plane according to DTK 5 and height deviations according to the DMV 5 are higher in areas with high vegetation. Positional differences in areas without vegetation were much less obvious.
