Directory of open data portals for Germany, Austria, Switzerland and Liechtenstein (D-A-CH-LI)

The directory of OpenGeoEdu data portals provides a central entry point for cross-platform searches or searches for open data and services. The access is either via the specially designed data portal, via a REST API or via download. With the web form of the portal, corrections and additions can be requested. In addition to open data and transparency portals, statistics, geo-, environmental and citizen science portals are also listed, which at least partially offer open or free offers. The data portals are also categorised according to reach and positioned at meaningful reference locations (mostly the publisher’s location) on a web map. The directory thus displays the open data infrastructures of the D-A-CH-LI space in their entire range and diversity. The data query of the REST API is analogous to the documentation of the PostgreSQL extension PostgREST (see http://postgrest.org/en/v7.0.0/) Query examples: http://portal.opengeoedu.de/api/portale (all dates) http://portal.opengeoedu.de/api/portale?id=eq.10 (Show portal with ID 10) http://portal.opengeoedu.de/api/portale?reichweite=eq.international&typ=eq.odp (Show international open data portals)
