From the World Wide Human Geography Data Working Group: "To help combat the spread of the Ebola virus disease, the National Geospatial-Intelligence Agency is providing unprecedented online access to its unclassified geospatial intelligence products to lead federal agencies and their partners through a public-facing website dedicated to the crisis. The dynamic site, which uses Esri's ArcGIS Platform hosted in the cloud by Amazon Web Services - both publically available services - features various base maps that provide foundational context for users, who will then have the ability to visually overlay public NGA data, as well as ingest open-source data. NGA's first exposure of data includes geospatial layers relevant to the Ebola outbreak in Guinea, including cultural places and structures, and communication, electric power and ground transportation infrastructure. The team will continue to update the site and will provide layers for the other affected countries soon."
