This from Esri… A Japan Trends Map is now available from Esri. The map visualizes a heat map of aggregated reports or reports categorized by property damage, hazards, evacuations, power outages, or help/services available. These can be filtered by date to see daily trends. By selecting “Show reports” you can see individual Ushahidi reports. Public content from Ushahidi is added to the site by directly accessing the Earthquake Tohoku service through the Ushahidi API. The Ushahidi platform allows anyone to gather distributed data via SMS, e-mail or the web and visualize it on a map or timeline. The feed aggregates information from the public for use in crisis response. Incidents are requested from Ushahidi in JSON format and add to the map based on the ArcGIS API for JavaScript.
