V diplomski nalogi je predstavljen eden izmed možnih pristopov izboljšanja položajne natančnosti digitaliziranih grafičnih katastrskih načrtov na osnovi t. i. membranske metode. Grafični katastrski načrti so zaradi tehnologije izmere, slabe matematične osnove, nekakovostnega vzdrževanja načrtov skozi zgodovino ter posledične nehomogenosti načrtov le pogojno primerni za strokovno rabo, zato je mnogo pozornosti usmerjeno v izboljšanje položajne natančnosti teh načrtov. V tem diplomskem delu je opisan pristop k izboljšanju položajne natančnosti zemljiško-katastrskega prikaza (ZKP) na območju katastrske občine Žažar in temelji na upoštevanju osnov geodetske izmere in izravnave opazovanj (metoda najmanjših kvadratov MNK, zakon o prenosu varianc in kovarianc ...). Opisan je celoten postopek določitve, identifikacije (na terenu) in geodetske izmere tako imenovanih veznih točk ter nadaljnja računska obdelava tako pridobljenih podatkov skupaj s podatki iz arhiva zemljiškega katastra s programskim orodjem Systra, ki se opira na načela t. i. membranske metode. Namen je predvsem oceniti ustreznost uporabe raznolikih veznih točk (mejna znamenja katastrskih občin, mejniki parcel ...), določiti njihovo optimalno razporeditev na študijskem območju ter izbrati najprimernejšo metodo geodetske izmere veznih točk za izboljšanje položajne natančnosti ZKP-ja. Na podlagi pridobljenih rezultatov izboljšave položajne natančnosti ZKP z membransko metodo se lahko nadalje izvede primerjava z že obstoječimi metodami (trikotniško odsekoma afina transformacija ...) in ocenijo prednosti in slabosti obravnavane metode.

• Title: Identification of tie points and improvement of the positional accuracy for land cadastre index maps, based on membrane method in the cadastral municipality of Žažar : graduation thesis: No. 885

Abstract

The diploma thesis presents one of the possible approaches to improve the positional accuracy of digitalized graphical cadastral maps based on membrane method. Graphical cadastral maps became practically useless or conditional applicable to professional use due to measurement techniques, mathematical foundations of cadastral surveying, poor maintenance through the history and consequently the heterogeneity of the cadastral index maps. Because of this, much attention has been focused on improving of the positional accuracy of these maps. This work describes the approach to the improvement of land-cadastral index map positional accuracy within the cadastral municipality of Žažar and is based on surveying principles such as measurements, adjustment (least square method, error propagation etc.). In the thesis, the entire process of determination, identification (in the field), surveying measurements of the »tie points« and their further processing together with other data from the land cadastre by the software tool Systra, based on the principles of membrane method, is described. The main purpose has been to evaluate the use of different identical (tie) points, to determine their optimal arrangement in the study area and to determine the optimal approach to measurements to determine their position for the purpose of improving the positional accuracy of land cadastral index maps. The results of the improved positional accuracy of land cadastral index maps in this study might be further used for comparative analysis with the results of other studies relating to the improvement of positional accuracy of land cadastral index maps, where the advantages and disadvantages of different approaches should be determined.
