The INSPIRE Geoportal is the European Union's central access point for spatial data published under the INSPIRE Directive, which harmonizes geographic data and services across all member states. It lets you discover datasets for standardized themes — from administrative units and addresses to hydrography, land cover, and protected sites.
Rather than hosting data, it indexes member-state services and links to authoritative national and regional sources, exposing them through interoperable OGC services. It is invaluable for cross-border European GIS work where consistent thematic coverage matters.
