Analysis of heights of mountain interesting peaks and other characteristic points in Slovenia

Namen diplomske naloge je predlagati rešitve za izboljšanje in poenotenje podatkov višin značilnih točk, ki se vodijo v bazi Planinske zveze Slovenije. Nadmorska višina značilnih točk, kot so vrhovi, sedla in izhodišča, je na različnih virih (razne planinske, turistične in topografske karte, topografske baze ter spletne strani) navedena različno. S statično metodo izmere GNSS smo določili 3D-položaj izbranim štirinajstim vrhovom, trem izhodiščem in dvema sedloma. Analizirali smo razloge za razlike med višinami, pridobljenimi iz različnih virov. Po pregledu vseh rezultatov smo ugotovili, da je do razlik največkrat prišlo zaradi napačne določitve horizontalnega položaja, napak pri prepisu s topografske podlage ali neustrezne izbire vira podatkov o višinah. Kot zanesljiv vir podatkov o nadmorskih višinah se je izkazal oblak točk reliefa, ki je rezultat laserskega skeniranja terena.The purpose of the graduation thesis is to propose solutions for improvement and unifying the data points that are kept in the database of the Mountaineering Association of Slovenia. The altitude of characteristic points, such as peaks, saddles and starting points, is stated differently on different sources (different mountain, tourist and topographic maps, topographic databases and websites). The static GNSS method was used to determine the 3D-position of the selected fourteen peaks, three starting points and two saddles. We analyzed the reasons for the differences between the heights from the topographic base and from the digital terrain model. After reviewing all the results, we found that the differences were most often due to incorrect determination of the horizontal position, errors in transcription from the topographic base or the choice of source for altitude data. A terrain point cloud, which is the result of laser scanning of the terrain, has proven to be a reliable source of altitude data
