Web applications make it easier for users to obtain and use geodata, provide data from the real estate cadastre and other information systems of the ČÚZK department directly in the web environment, without the need to purchase own software.

Applications can be divided into the following groups:

• application for providing geodata, i.e. access to download or request for issuance or modification
• applications and services for providing data from the real estate cadastre
• applications and services for providing data from the Register of Territorial Identification of Addresses and Real Estate (RÚIAN)
