datos.gob.es is the catalog of open data for Spain's public sector, federating datasets from the central government, autonomous communities, and local entities. It is the national discovery point and connects to Spain's spatial data infrastructure (IDEE).
Coverage includes administrative boundaries, addresses, transport, environment, and statistics, generally under open terms permitting reuse. For authoritative cartographic base data and reference geographies, the National Geographic Institute (IGN/CNIG) provides downloadable products.
