Our mapping response in West Africa due to the Ebola epidemic there continues. The Bing high-res imagery is the main source for tracing the OpenStreetMap. But it was not available in some areas where the epidemy is concentrated. CartONG first bought three images from Airbus Defense & Space for Gueckedou, Kissdougou and Macenta. To complete the mapping of the region we also looked at obtaining some other imagery. Thanks to Mapbox / DigitalGlobe who donated the Imagery for Mamou town. Thanks to Airbus Defensce and Space who offered new imagery covering 14,000 sq.km for the region of this Ebola Outbreak. This has given us the opportunity to complete the tracing of the highway network of the region most affected by this Outbreak. Thanks also to Jean-Guilhem Cailton who obtained and processed this new imagery.
Various media organisations are reporting on the OpenStreetMap community efforts to map remotely in support of the humanitarian organizations on the ground. While no detailed map of the area existed before this event, we now see a significant progress in mapping of the region.
Guinea58.com, a Guinean media organisation, is presenting the OSM community contribution to the local population and summarizes the various medias updates on the subject. See the Ebola Response Media coverage.

CartONG who makes the bridge with MSF CH is addressing to the HOT - OSM community the appreciation of MSF-CH for the community support to the response to the ebola outbreak in Guinea and surrounding countries. The mapping was a huge help for the outreach teams, and for many expats newly arrived and needing a briefing on how the outbreak is evolving. Finding remote localities and access to them is often a race against time as a few hours can make a serious difference, not only for patients, but also to arrive in time to prevent new contacts to happen and keep the outbreak from spreading further. Cross-checking between local knowledge and OSM maps allows the teams to work much faster. Regarding locality names in OSM, the MSF teams were able to acquire through various field trip with GPS devices a confirmed database of localities covering the sub-prefectures of Gueckedou-Centre, Temessadou-Dibo, and Guedembou. This information will be very useful to revise the OSM database and provide an essential information to the various teams operating in the area. The Guinea / Liberia : Ebola Outbreak Mar.2014 report from Reliefweb links to the 2014 West Africa Ebola Response HOT wiki page that lists the maps and the various OSM services. These various products help also PAM, UNICEF, IFRC/ARC and through them WHO, Government and NGOs.
