Abstract

V diplomski nalogi je obravnavana vzpostavitev geodetske mreže na Ljubljanskem gradu, ki predstavlja koordinatno osnovo morebitnega zajema gradu s tehnologijami terestričnega laserskega skeniranja. Cilj naloge je vzpostavitev geodetske mreže v državnem koordinatnem sistemu z natančnostjo točk boljšo od 2 mm. Diplomska naloga je zajemala terenske meritve z GNSS RTK-metodo izmere, kakor tudi s klasično metodo izmere, kjer smo meritve horizontalnih smeri izvedli po girusni metodi, višinske razlike pa so bile določene z metodo trigonometričnega višinomerstva. Uporabili smo GNSS instrument Leica Viva GS15 ter tahimeter Leica Nova MS50. Da smo pridobili vpogled v kakovost opravljenih meritev, smo izvedli ločeno višinsko in horizontalno izravnavo geodetske mreže. Ker se izravnane natančnosti navezujejo na center prizme, želeli pa smo natančnosti točke na tleh, smo te vrednosti popravili za vpliv pogreška centriranja in pogreška merjenja višin instrumenta. Tudi ob upoštevanju tega faktorja je cilj diplomske naloge izpolnjen, saj znaša srednja vrednost natančnosti koordinat 0,51 mm in srednja vrednost natančnosti višin 1,12 mm.

Secondary title: Establishment of a geodetic network at the Ljubljana Castle
Secondary abstract: In the graduation thesis, we deal with establishment of a geodetic network at Ljubljana Castle, which represents a coordinate foundation of a potential capture of the castle using technologies of a terrestrial laser scanning. The objective of the thesis is to establish a geodetic network in a state coordinate system with the accuracy of points better than 2 mm. The graduation thesis encompassed field measurements using GNSS RTK-measurement method, as well as a classical measurement method in which measurements of horizontal directions were performed using girus method, and height differences were defined using a trigonometric altimeter method. We used GNSS Leica Viva GS15 instrument and Leica Nova MS50 tacheometer. In order to obtain insight into the quality of the performed measurements, we performed separate vertical and horizontal adjustment of the geodetic network. As the adjusted accuracies are related to the centre of the prism, but we wanted the accuracy of a point on the ground, we corrected these values for the influence of the centring error and errors of the instrument measuring heights. Even when considering this factor, the objective of the graduation thesis is fulfilled, as the average value of the coordinates% accuracy is 0.51 mm and the average value of the heights accuracies is 1.12 mm.
