The Spanish cadastre is an administrative register with a fiscal origin, created as a data bank to be accessed both by Public Administrations (national, regional, local) and citizens. As an inventory of real estate, it contains physical information (surfaces, location, use, shape, boundaries, cartographic representation, crops and forest use, type and quality of constructions, etc.), legal information (identification of holders or owners: name, national identification number, address, etc.) and economic information (cadastral values of land and buildings, valuation criteria). This cadastral bank includes detailed information of more than 32 million urban properties, more than 40 million rural properties and more than 27 million cadastral owners. https://ovc.catastro.meh.es/CYCBienInmueble/OVCConsultaBI.htm
