The diploma thesis presents the process of homogenization of positional accuracy of land cadastral index map, where the so called membrane method as one of the possible approaches to achieve the goal of homogenization has been used. In Slovenia, the cadastral index maps are characterized by considerable inhomogeneity as a result of different technologies used for land surveying and maintenance of cadastral maps during several decades. In this thesis, the software solutions of Slovenian providers are presented, which are most frequently used in the land cadastre, and the software solution from the German providers is introduced, which was used in this research for
homogenization of positional accuracy of cadastral index map. The whole process is presented starting with data acquisition, data processing, adjustment computation to the analysis of results, we obtained with Systra software. The main purpose was to determine the optimal number of observations of additional land cadastral points, which determine the land plot border, to achieve improvement of
positional and geometrical accuracy of the cadastral index map in the study area of cadastral community Bočna. The particularity of the study area is that there was a new cadastral surveying conducted, which included also the land plots’ rearrangements, and this has definitely bought some
specialities when dealing with the geometrical and positional characteristics of the cadastral index map.
