= All the addresses of owners residing permanently in 
Slovenia had to be encoded with respective address 
codes from the Register of Spatial Units. 
= The total of ownership shares indicated in title sheets 
had to be 1. 
= The land use codes that applied to land parcels had to 
comply with the code list set forth in the Catalogue. 
In order to facilitate the harmonization of data with the 
defined standards, supporting software was developed for 
every municipal surveying and mapping authority. 
The Joint Database of the Land Cadastre including data for 
the whole of Slovenia was set up following a uniform 
principle in 1995. 
The following step in the modernization of the Land Cadastre 
was the informatization of procedures and the entire 
graphical part of the Land Cadastre. The common goal was 
to set up a uniform digital database of Land Cadastre data 
based on the existing analogue form, to ensure the continuity 
of operation with a natural transition from manual to 
automated administration of the Land Cadastre, and to 
improve the quality of data and operation of the Land 
Cadastre. 
Therefore, it was necessary to differentiate and define the 
fundamental entities of the digital database of the Land 
Cadastre in the initial informatization analysis. The said 
entities were as follows: land parcel (in the textual and the 
graphical part), title sheet, land owner, land cadastre point, 
and land parcel boundaries; cases that could be turned into 
administrative procedures and result in the preparation of a 
cadastral study were also important for the administration of 
procedures. 
The definition of the fundamental entities was followed by 
the definition of uniform procedures for entity administration 
and updating. The fundamental Land Cadastre procedures 
were defined in the period between 1991 and 1994 in 
compliance with the regulations in place at that time. One of 
the most important achievements of the period was the 
uniformity of a wide range of different IT solutions used in 
individual municipalities or groups of municipalities. The 
uniformity was achieved in reference to administration of 
procedures, receipt of applications, sending of invitations to 
owners, preparation of data for field surveys, preparation of 
cadastral studies, controlling of cadastral study reliability, 
numbering of cadastral procedures, decisions and documents 
making part of administrative procedures. Uniformity was 
also achieved in reference to the organization of Land 
Cadastre archives. This resulted in the creation of a record of 
cadastral studies. Uniformity also applied to the definition of 
the Land Cadastre point and the geodetic control point 
including all of its characteristics that are in place today. In 
parallel with the achievement of uniformity, preparations 
were made for the implementation of informatization, which 
implied the drafting of required technical and technological 
documentation. 
Original plans have foreseen the preparation of a uniform IT 
solution for the administration of the database and procedures 
of the attribute and graphical part of the Land Cadastre. 
However, the idea was never materialized in practice, 
because it required that textual and graphical information be 
harmonized in the digital database, which was not feasible.

Further development was directed towards specific software 
solutions that were based on the quality of the existing 
analogue and digital data. The development of software 
solutions went in two separate directions providing support 
either to the attribute part or the graphical part of the Land 
Cadastre. Nevertheless, further developments have also 
integrated element allowing the harmonization of the two. 
The development of software solutions for the attribute part 
of the Land Cadastre was first aimed at creating a record of 
cadastral studies and a database of Land Cadastre points. The 
second stage involved the linking of the two records and their 
upgrading so as to allow the management of comprehensive 
procedures. 
The creation of the record of cadastral studies and of the 
database of Land Cadastre points were the first steps on the 
way to informatizing Land Cadastre procedures. The most 
important step is the design and development of the software 
package for the administration and updating of the attribute 
part of the Land Cadastre, from receipt of application to the 
issue of administrative decision. It allowed the browsing of 
the database of land parcels, title sheets, land owners, of the 
record of cadastral studies and the database of Land Cadastre 
points. At the same time it permits the registration of 
applications received, production of invitations to owners to 
attend field surveys, issuing of data for the needs of data 
changing in the Land Cadastre, the cross-sectioning of data, 
official annotation of land parcels, reservation of land parcel 
identification numbers and identification numbers of Land 
Cadastre points, integration of changed data, two-way 
controlling of changed data and controlling of the changes 
implemented in relation to existing data, as well as the 
reviewing of all phases of the procedure. The implementation 
of the software package at all Branch Offices of the 
Surveying and Mapping Authority of the Republic of 
Slovenia was finally completed in the second half of 1998. 
The enforcement of the Real Estate, State Border and Spatial 
Units Registration Act in 2000 was followed by a major 
partial redesign in software operation, which now complies 
with the provisions of the new legislation. 
Graphical Data of the Land Cadastre 
The first cadastral map digitisation tests were carried out at 
the end of 1980's, but the surge in data harvesting activities 
did not follow. The first digitisation procedures were devised 
in the beginning of 1990's. 
The procedures were defined by 1993 and they included the 
scanning of cadastral maps, edge-matching, vectorization, 
collating of vectored map sheets for individual parts of 
cadastral units, and the implementation of controls over the 
matching of the textual and graphical information of the 
Land Cadastre. The procedures were defined for the 
graphical and numerical cadastre. The high level of 
discordance between data required the development and 
implementation of another software package. It enabled the 
harmonization of Land Cadastre data in all of the fields of 
application listed above. 
Data capture based on digitisation gained momentum after 
1995, when all major surveying and mapping companies 
started capturing data in this fashion.
