ZABAGED® - planimetric components - introduction

The Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®) is a digital vector geographic model of the territory of the Czech Republic (CR), which is administered by Land Survey Office in the public interest. ZABAGED® is a part of the Information System of Land Surveying according to Act No. 200/1994 Collection of Laws of the Czech Republic as amended. Detailed content and administration are determined by the Regulation of COSMC No. 31/1995 Coll., as amended, implementing the Act No. 200/1994. List of the feature types including their definition, data sources, geometric representations, attributes, identifiers into  other information systems of public administration is published in Katalog objektů ZABAGED® (pdf), (web version).
ZABAGED® is used as a base layer in geographic information systems (GIS), primarily in information systems of the public service. It is also the main data source for creation of base maps of the CR at scales of 1:10 000 to 1:100 000. Currently selected feature types of ZABAGED® are used for INSPIRE data structure. On the base of user needs, the ZABAGED® content is gradually being expanded and refined, including geometrical position of elements.

At present, ZABAGED® consists of 128 types of geographic objects classified in planimetry or altimetry section of ZABAGED®. Information about altimetry section of ZABAGED® can be found in folder ZABAGED®- altimetry.

Planimetry section of ZABAGED® contains two dimensional (2D) spatial information and descriptive information on settlements, comunications, utility networks and pipelines, hydrology, administrative units and protected areas, vegetation and surface, terrain relief. It includes selected data on geodetic reference points within the territory of CR. It consists of 125 types of geographical objects. It is maintained as a seamless database for the entire territory of the CR in a centralised information system managed by the Land Survey Office.

Production of ZABAGED® began in 1995 by vectorization of prints of BM 10, but conceptual preparation works had taken place before that date. ZABAGED® was completed in the whole range of pre-defined feature types and in the entire territory of the CR in 2004. Chronological information about  ZABAGED®  foundation and its development till 2014 was published in the article Základní báze geografických dat (ZABAGED®) - dílo jedné generace českých zeměměřičů [Fundamental Base of Geographic Data (ZABAGED®) – The Work of One Generation of the Czech Surveyors], in  magazine GaKO, volume 62/104, 2016, number 4.

Since the beginning of existence of ZABAGED® the feature types have been regularly revised and updated in two principal ways. Periodic data updating has been in process on the base of remote sensing methods, contact with municipalities, available internet information and topographic field surveys. Great emphasis is also being put on the use of outputs from public administration information systems. Therefore, the second way for data updating - Continuous data updating is based on using external data. Selected feature types have been updated continuously in cooperation with primary administrators of this data. Update Status Reports, see tables Periodic Update Status table and Continuous Update Status table, which also contains a list of external sources.

ZABAGED® data have been geometrically refined thanks to more accurate remote sensing outputs and other resources. Between 2013 and 2019, targeted systematic geometry position improvement of selected feature types was held on the base of data from aerial laser scanning. The project focused on registered roads and motorways, railway lines, watercourse axes and bank lines, significant terrain edges, heights points, including topologically linked elements. In 2015, a comprehensive revision and geometry refinement of constructions, especially buildings, was started using mainly data from Information System of the Cadastre of Real Estate (ISKN). The status and process plan (including update schedule) can be found here.

Some feature types contain so-called identifiers as an attribute which forms an integration key to find more detailed information about a geographic object in the primary external data source. This creates the pre-requisites for integration of ZABAGED® within the public administration information system.

Due to the content and geometric inconsistency of information provided by individual primary geographic data administrators, the Land Survey Office ensures their harmonization so that ZABAGED® forms a complex, topologically harmonized geographic model of the territory of the Czech Republic.

Information on products available for provision of ZABAGED® data sets can be found in the right-hand menu on this page.

ZABAGED® is made available using map viewing and download services on which you can find information in the Web services section.

Viewing services are freely available in all applications (clients). The map window at introduction page of Application section at the CUZK Geoportal or Geoviewer client can be exploited to display them.

To order data and download WFS service you can use the internet shop.
