About

Application

This application is powered by ArcGIS Server. The ability to add content is provided by ArcGIS Server 10 hosted in the Amazon Web Service infrastructure.

ArcGIS Online Basemaps

This application includes basemaps from ArcGIS Online including:

• Streetmap—It includes highway and street-level data for the entire country.

• Satellite Imagery—The ArcGIS Online World Imagery basemap presents satellite imagery for the world and high-resolution imagery for the United States, Great Britain, and hundreds of cities around the world.
• Topographic Map—The ArcGIS Online World Topographic basemap  (aka "the community basemap") includes boundaries, cities, water features, physiographic features, parks, landmarks, transportation, and buildings.
• Open Street Map (OSM)—OpenStreetMap is a free editable street map of the whole world. OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere around the world.

Layers

• News Feeds: We gather the headline news from various online news agencies and pass each link through the RSStoGeoRSS web service. This service can geocode RSS content from any RSS Web link and return the content as GeoRSS. We use the Aggregated Live Feeds methodology to take the returned GeoRSS XML and serve it through ArcGIS Server as a map service.
• Ushahidi: This 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. We request the incidents from Ushahidi in JSON format and add to our map based on the ArcGIS API for JavaScript.
• YouTube Videos: The videos are added to the application using the YouTube API. The YouTube data API allows you to request videos given a latitude and longitude position along with a search radius and keywords. From here we parse the response from YouTube and use the coordinates with each returned record to draw the point and incorporate the results into the ArcGIS API for JavaScript InfoWindow.
• Tweets: The Twitter API is used to identify tweets that match a specified query and area. In this case, only the tweets that return a coordinate value within the current visible map extent are added to the map. The Twitter API sends the results of the query back to the application as JSON, which is easily incorporated into the ArcGIS API for JavaScript.
• Flickr: The Flickr API is used to identify Flickr photos that match search terms and a collection of other parameters identified in the Flickr API help pages. The Flickr API sends the results of the query back to the application as JSON, which is easily incorporated into the ArcGIS API for JavaScript.
• Earthquake locations: Earthquake data is provided by the Pacific Disaster Center (PDC) as part of the active hazards map service. The data are dynamically updated in real-time.
• ShakeMap: ShakeMap is a product of the U.S. Geological Survey Earthquake Hazards Program in conjunction with regional seismic network operators. ShakeMap sites provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and disaster planning.We gather this data from the USGS xml feed. These shape files from the xml feed are parsed using the Aggregated Live Feeds methodology to take the returned information and serve the data through ArcGIS Server as a map service.
