Dataset for the theme Buildings (BU) harmonised according to the INSPIRE Directive and ELF Data Specification version 1.0. Data contains buildings and building parts. Building parts necessary for INSPIRE implementation are represented by entrances and come from RÚIAN. Entrances contain technical-economical attributes and other information. The data set covers the whole area of the Czech Republic. It is provided as Open Data (licence CC-BY 4.0). Data comes primarily from the project RÚIAN (Register of Territorial Identification, Addresses and Real Estates) and partly from ISKN (Information System of the Cadastre of Real Estates). .41%, i.e. 17600 of buildings do not contain centroid or polygon (to 2024-12-02) and therefore are not included in the dataset. Data is created daily via individual municipalities (if any change within the municipality occurs), provided in the GML 3.2.1 format and is valid against XML Definition Schema for the theme Buildings in version 4.0. Dataset is compressed (ZIP) for downloading.
