ABSTRACT: 
In the last decade the Surveying and Mapping Authority of the Republic of Slovenia has succeeded in collaboration with Slovene 
company experts to substantially redevelop and adjust individual parts of the Land Cadastre, and to digitise its textual and graphical 
content. Information Technology (IT) solutions were developed for administering and updating Land Cadastre data and for updating 
data through administrative and technical procedures. A significant objective of the entire process of informatization is the creation 
ofthe Central Database of the Land Cadastre. 
The creation of the Building Cadastre ran in parallel with the development of the said central database. The content of the Building 
Cadastre was defined in detail and all the necessary legislation was enacted. The IT solution used for administering and updating the 
Building Cadastre was developed as well. All the buildings in Slovenia were identified, and building footprints have been captured 
over the last three years. The main objective of this year's activities is to capture textual data on buildings. 
The main objective to be reached in the years to come is the modernization of the real-estate information system. The existing 
information solutions in the field of real-estate registers will be redeveloped and made uniform. 
INTRODUCTION 
Over the last ten years the Slovenian national land survey 
service has taken a significant step forward in terms of 
development. In this period geodesy in Slovenia has achieved 
considerable technological progress in the field of the 
geodetic and cartographic systems, surveying methods and 
techniques, and real estate registration. Major changes have 
occurred in the scope of activities, which reflects in the 
expansion of real estate registration, topographic and 
cartographic databases, etc. Important organizational changes 
have also occurred centralising the administration part of the 
national land survey service and privatising the rest of the 
geodetic activities. The article does not aim to describe the 
entire development process of geodetic activities. It is limited 
to the aspects that are more important, i.e. the technological 
and the substantive aspects of development of real estate 
registration, or to be more precise, to the development of the 
Land Cadastre and the Building Cadastre. 
INFORMATIZATION OF THE LAND CADASTRE 
Attribute Data of the Land Cadastre 
At the end of 1980's and at the beginning of 1990's, the 
registration of land and titles was regulated in accordance 
with the legislation that was in place in that period. From the 
technological point of view, real estate registration was done 
manually, a portion of the attribute part of the Land Cadastre 
was kept in different digital formats, and the registration of 
buildings and parts of buildings was not adequately 
regulated. In practice, data on buildings and parts of 
buildings was not collected. 
This period is characterized by a great variety of Land 
Cadastre data administration methods that were implemented 
by Branch Offices of surveying and mapping authority.

There was also a variety of IT solutions applied in the 
administration of the attribute part of the Land Cadastre. 
The circumstances described above had triggered the 
implementation of activities that were aimed at making 
uniform the IT solutions used for administering and updating 
attribute data of the Land Cadastre. This was the reason why 
as early as in 1989 the National Surveying and Mapping 
Authority appointed a working party for the development of 
Land Cadastre Standards. The first Catalogue of the Basic 
Land Cadastre Data Standards was published in 1991. 
The Data Catalogue was developed so as to allow the linking 
of Land Cadastre data with other state records that were not 
under the jurisdiction of the national land survey service. 
Based on the Catalogue the Statistical Office started creating 
the Joint Database of the Land Cadastre which was linked to 
the Central Population Register allowing an automated 
transfer of data to the Tax Administration. 
The development of software used for administering attribute 
data on land parcels was based on the new Data Catalogue 
and the Joint Database of the Land Cadastre administered by 
the Statistical Office. This software facilitated to the 
municipal surveying and mapping authorities to implement 
the standard IT solution. The application of the new uniform 
software, which also implied the transfer of data into the 
Joint Database of the Land Cadastre, was a gradual process 
due to the conditions that had to be met by the databases 
administered on the local level. These conditions were as 
follows: 
= All owners had to be identified through a personal 
identification number, which ensured the linkage with 
the Central Population Register. In cases when owners 
could not be identified in the Central Population 
Register (especially foreigners), they were assigned 
temporary personal identification numbers in 
compliance with the uniform rules that were set forth in 
the Catalogue.
