= 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.
Further developments in the use of Land Cadastre
