Esri is serving a Libya Unrest map application that disseminates information being sent via Twitter, YouTube, and Flickr. The social media layers allow for custom keyword searches. Streetmap, OpenStreetMap, satellite imagery, and topographic maps are part of the map overlay.
The public Ushadihi layer shows mapped reports. Additional map layers added as data becomes available. This map can be embedded in online articles – See http://www.esri.com/news/maps/libya-protest-map-2011/
