The extension targets on providing full cadastral map as defined in Cadastral Public Note in the form of vectror data in the structure fully conform to the INSPIRE Directive and Implementing Rules. The data extends the INSPIRE Data Specification for the theme Cadastral Parcels (CP) for easements, geodetic points, other features, original geometry and analogue cadastral parcels (those in the areas with analogue map only). It originates in the cadastral map that is a binding national map series at large scale, contains points of horizontal geodetic control, planimetric component and map lettering and can be maintained in the form of digital map, analogue map or digitized map. The data published in the frame of this product contain cadastral districts (for the whole Czech Republic), parcels, their boundaries, easements, other features, geodetic points and original geometries from the territory where the digital map occures (to the 2019-10-21 it is 96.61% of the Czech territory, i.e. 76 196.37km2) and analogue cadastral parcels in the areas with analogue map, containing only reference points as geometry. More in the Cadastral Law 344/1992 Coll., Cadastral Public Note No. 26/2007 Coll. as ammended and INSPIRE Data Specification on Cadastral Parcels v 3.0.1. Data in the GML 3.2.1 fotrmat are valid against XML Definition Schema for the Cadastral Parcels Extended in version 4.0.
The cadastral map in the form of digital or digitized map was created at the renovation of the cadastre by new mapping or revision of analogue maps or it is a result of tranformation of digital representation of analogue map in S-JTSK datum to digital form. Rest of the area is covered by analogue map. The cadastral map is maintained (updated) continuously. Shapes of all cadastral zonings are already digitized. Cadastral parcels and their boundaries are published only for the territories where a digital map exists. In the territories without digital or digitized map, cadastral parcels are published with reference point instead of polygon. It also does not contain graphical map features, such as symbols or arrows. No cadastral districts or parcels overlaps. National cadastral reference is created by the number of cadastral unit, dash and number of the parcel including both parts. In cadastral units where the parcels of land and building parcels are numbered in two rows, for the building parcels "st. " is added to be possible to distinguish them from parcels of land. The number of cadastral unit and parcel is provided separately in the Czech legislative, i.e. not with a dash as in the national cadastral reference. Historic data are not included in this product, but it contains easements, geodetic points, other features and original geometry segments.
