Information System for the Cadastre of Real Estate

Published on: 10/01/2016

The Czech Republic’s Information System for the Cadastre of Real Estate is operated by the Czech State Administration of Land Surveying and Cadastre. The online service makes it easy to get access to information about real estate, since users no longer have to visit the registry’s offices. Any user can immediately view information on the ownership of land, buildings, units (flats or offices), and the legal details of all real estate. Part of the data is available for free, but the Registry also operates a paid remote-access service intended for the professional community. Source data used by the applications is updated daily.

Policy Context

Information System for the Cadastre of Real Estate

The Cadastre of Real Estate (Katastr nemovitostí, KN) is one of the largest government information systems in the Czech Republic, as measured by the amount of data it contains. Digitization of the Cadastre’s ‘File of Descriptive Information’ was completed in 1998, and digitization of the ‘File of Geodetic Information’ is now under way.

The Information System for the Cadastre of Real Estate (Czech: Informační systém katastru nemovitostí, ISKN) is an integrated information system designed to support the state administration’s duties and provide services to users in the area of the Cadastre of Real Estate. The Information System (IS) allows the files of descriptive and geodetic information to be administered, and supports the administrative activities of the Cadastre of Real Estate itself as well as its resources of documentation. The IS is a centralized system with a single database, which connects to the various Cadastral Offices via an internal network.

Description of the way to implement the initiative

Data Administration

The main strength of the IS is its implementation of a sequence of automatic checks during the process for registering changes in the Cadastre of Real Estate. The system also has the advantage of using up-to-date data from the system of basic registers and other state administration information systems.

Administrative activities that need to be completed when changes to the Cadastre of Real Estate are registered can be performed using electronic communication systems and electronic documents. Changes submitted by executors or notaries (via the web application at or in person) are automatically processed by the IS. The system’s built-in interconnection with the Integrated System of Data Boxes facilitates electronic communication with clients.

Data and Service Provision

The tools for data provision enable the Cadastre to receive up-to-date data immediately, and to publish this data in turn, both within the cadastral offices and via the Remote Access application (Czech: Dálkový přístup, DP). The Remote Access application provides data and services over the Internet; depending on the type of customer, the data is provided either for a fee or free of charge (for public administration bodies). Documents and maps from the Cadastre are protected by an electronic watermark; only authorized persons (notaries, the Czech Post, and especially CzechPoint workplaces) can convert these from their electronic form into official printouts. At present, more than one-third of all excerpts from the Cadastre are provided in this way, i.e. with a watermark. The Cadastre data is provided to the public in the form of datasets with a defined structure and format.

Technology solution

Cadastre of Real Estate of the Czech Republic

The Cadastre of Real Estate is a set of data about land parcels and buildings in the Czech Republic, including their position, shape, description and inventory. The Cadastre includes records of property and other legal rights to these pieces of real estate. The Cadastre contains all the necessary data about parcels of land, selected buildings, and their owners.

The Cadastre is a source of information that records rights to real estate for the purposes of taxes and fees, and protects agricultural land, forests, natural resources and cultural monuments. It is used for urban planning, for the valuation of real estate, for scientific, economic, and statistical purposes, and finally as a basis for other information systems.

The Cadastre is administered – mainly through the use of computers – as an information system covering the territory of the Czech Republic. A cadastral unit is the basic territorial unit, documented through a minimum of two files:

  • The file of geodetic information encompasses the cadastral map, including its digital representation in given cadastral units.

  • The file of descriptive information includes data about cadastral units, parcels, buildings, flats and non-residential premises, owners and other interested parties, legal relations and rights, and other points of law.

Data from the Cadastre is provided as public documents by the Cadastral Offices. A consultation procedure provides free access to selected information about registered parcels and buildings, including information about their owners, as well as information about the state of some proceedings in the Cadastral Offices.

For paying users, the data is also available via the Remote Access system (see below), and in bulk form using a standardized exchange format. Copies of cadastral maps are also available in raster form.

Remote Access via the Internet

Remote Access is a paid service that gives registered users online access to data from the Cadastre of Real Estate. It is provided by the Czech Office for Surveying, Mapping and Cadastre.

Outputs from the Cadastre acquired in this way (known as ‘excerpts’ from the Cadastre of Real Estate) are formally identical with the documents issued by the cadastral offices.

Data provided via Remote Access can be considered completely up-to-date because content changes in the Cadastre are immediately recorded in the Cadastre’s central database. Changes in this database are then transferred to the Remote Access database at 20-minute intervals.

Remote Access users are mostly people and organisations who expect to use the service frequently. Individuals who need only occasional output from the Cadastre can be served by any cadastral office, regardless of location.

The Remote Access application runs continuously and has emergency systems in place to ensure continued operation in the case of equipment failure, according to the Office for Surveying, Mapping and Cadastre. To protect the system, the number of simultaneous users is limited. So far, however, the limit has been more than sufficient and no users have been refused access due to overload.
