Geoportal Baden-Württemberg is the official information and communication platform for geodata in the German state of Baden-Württemberg, serving as the central access node to the state's spatial data infrastructure (GDI-BW). It is operated by the State Office for Geoinformation and Land Development (LGL).
It lets you visualise and combine base maps, aerial imagery, cadastre, zoning plans, nature reserves, flood, geology, and many thematic layers. The LGL distributes selected base geodata as free open data via its Open GeoData portal and OGC web services.
