Covid-19 Datenhub vs Humanitarian Data Exchange

Robert Koch Institute's ArcGIS Hub aggregating dozens of official German COVID-19 datasets — case, death, vaccination, and hospitalisation figures by Kreis and Bundesland — each independently queryable as a standard Esri ArcGIS REST Feature Service rather than through one unified endpoint. A live query against the flagship RKI_COVID19 FeatureServer (services7.arcgis.com) returns Access-Control-Allow-Origin: *, resolving the stored 'unknown' cors to 'yes'.

HDX is OCHA's CKAN-based catalog of over 18,000 humanitarian and public-health datasets (disease outbreaks, health-facility locations, population and displacement data) covering 250+ locations, searchable and downloadable through the standard keyless CKAN Action API (package_list, package_show, datastore_search). A live GET against data.humdata.org/api/3/action/status_show succeeds with no key, and a live Origin-header probe returns Access-Control-Allow-Origin: *, resolving the stored 'unknown' to 'yes'.
