The developers of Gaia GPS app http://www.gaiagps.com/ have made available a special application for Haiti responders. now available in the iTunes shop (kudos for getting it in there so fast!) this special version of the app has been developed specifically for the Haiti response and for Haiti responders. The app can be used to download and display maps and satellite imagery of affected areas as well as up to date overlays showing important information and POIs. Map data has been provided by OSM, Digitalglobe, GeoEye, and the map data is hosted by the NY public library. See Gaia GPS in the app store for the app. For more Haiti GIS and mapping resources see this list of data resources we just released.
