In this master's thesis, we have studied the cadastral procedures of land arrangement and land re-arrangement, which are being regulated under current Slovenian legislation. The initial part is consisted of a theoretical background in the field of land re-arrangement together with a brief historical overview of a land cadastre establishment and its maintenance in Slovenia. This kind of knowledge is important for understanding the diverse quality of cadastral data. We continued with a past researches review about land arrangement and land re-arrangement followed detailed presentation of the legal framework stipulating new cadastral survey, setting-up of land cadaster and land consolidation. These cadastral procedures are known as mass cadastral procedures of land arrangement and re-arrangement based on the current Slovenian legislation. Additionally, we described Croatian experiences with implementing new cadastral survey. What follows next is a detailed analysis of the procedures for the cadastral land arrangement and land re-arrangement in Slovenia. A significant result of the master’s thesis is a comparison between legal criteria for introduction and implementation of individual and mass cadastral procedures in Slovenia. For a better understanding of the discussed procedures and critical evaluation of the current legal provisions, we conducted a study of the new cadastral surveying and the setting-up of land cadaster using practical examples in Slovenia. Based on the analysis of existing statutory provisions and practical examples we were able to form and suggest improvements of criteria contents presented at the end. Emphasis is placed on two of mass cadastral procedures, namely a new cadastral survey and setting-up of the cadastre. Our purpose was to point at unexploited potential and their expected future contribution to data quality of land cadastre and effectiveness of land re-arrangement.
