V magistrski nalogi smo v dveh terminskih izmerah s kombinirano GNSS in klasično terestrično izmero ter laserskim skeniranjem določili potek soteske Mlačca in jo umestili v državni geodetski referenčni sistem. Cilj naloge je, da določimo debelino ledu v sezoni 2019/2020, ki bo služila za izhodišče primerjave debelin ledu v nadaljnjih sezonah. Že med izmerami je bilo očitno, da v letošnji zimi ni bilo pogojev, da bi soteska zaledenela v tolikšni meri, da bi bilo mogoče lednim plezalcem zagotoviti varno ledno plezanje po plezališču. Pri izdelavi magistrskega dela smo se osredotočili na dva cilja, ki se med seboj prepletata in povezujeta. Prvi in glavni cilj naloge je analiza zajetih skenogramov terestričnega laserskega skeniranja ter že obstoječih prostorskih podatkov aerolaserskega skeniranja za območje Republike Slovenije. V drugem delu dela pa smo se osredotočili predvsem na problem, kako lahko tretji osebi oziroma laičnemu uporabniku prikažemo ogromno količino prostorskih podatkov. Glavni cilji takega okolja so predvsem enostavna, razumljiva, kakovostna, hitro učljiva in dostopna aplikacija, s katero bo potencialnim uporabnikom omogočen dostop do pregleda in izvajanja osnovnih merjenj v izdelanem interaktivnem okolju.

• Title: Evaluation of the ice wall thickness from geodetic measurements in Mlačca : master thesis no.: 111/II. GIG

Abstract

In this master`s thesis, we determined the course of the Mlačca Gorge in two term measurements with combined GNSS, the classic terrestrial measurement, laser scanning and placed it in the national coordinate base. The aim is to determine the thickness of the ice in the season 2019/2020, which will serve as a starting point for comparison of the ice thicknesses in further seasons. During the measurements, it was already obvious that this winter there were no conditions for the gorge to be icy to such an extent that ice climbers could be provided with safe ice climbing on the climbing area. In the master's thesis, we focused on two goals that are intertwined and interconnected. The first and main goal of the task is the analysis of the captured scans of terrestrial laser scanning, and already existing spatial data of aerolaser scanning for the territory of the Republic of Slovenia. In the second part of the work, we mainly focused on how we can show a huge amount (Big data) of spatial data to a third party or a lay user, without any use of demanding software. The main goals of such an environment are, above all, simple, understandable, high-quality, fast-learning and accessible application that will enable potential users to access the review and perform basic measurements in an interactive environment.
