About

This application is powered by ArcGIS for Server.

Basemaps

• Streetmap—This street map includes highway-level data for the world and street-level data for the United States, Canada, Japan, southern Africa, and a number of countries in Europe and elsewhere.
• Satellite Imagery—This map presents satellite imagery for the world and high-resolution (1m or better) imagery for the United States, Great Britain, and other areas around the world
• Topographic Map—This map includes administrative boundaries, cities, water features, physiographic features, parks, landmarks, highways, roads, railways, airports, and buildings overlaid on land cover and shaded relief imagery for added context.

Layers

• News Feeds: We gather the headline news from various on-line news agencies and pass each link through the http://ws.geonames.org RSStoGeoRSS web service (http://www.geonames.org/rss-to-georss-converter.html). We use the Aggregated Live Feeds methodology to take the returned GeoRSS XML serve the data through ArcGIS Server as a map service.
• Wildfire locations: This layer is part of the United States Geological Survey’s (USGS) Natural Hazards Support System (NHSS) Active Hazards layer available at http://nhss.cr.usgs.gov. The service contains data and information from a variety of public data sources, including non-USGS data. Therefore detailed information about each of these data providers, including specific data source, data currency and disclaimers, is provided at http://nhss.cr.usgs.gov/data.shtml.
• MODIS hotspots: MODIS Global Fires is a product of The University of Maryland's Fire Information for Resource Management System (FIRMS). FIRMS integrates remote sensing and GIS technologies to deliver global MODIS hotspot/fire locations to natural resource managers and other stakeholders around the world. Full layer description.
• Precipitation: We use Televent/DTN MxInsight software to download current precipitation from a DTN/Meteorlogix FTP server. We then use the Aggregated Live Feeds methodology to take the returned shapefiles serve the data through ArcGIS Server as a map service.
• Fire Potential: Wildland Fire Potential delineates areas based on fire intensity, weather, frequency, and size, which was then classified into a relative ranking of fire potential from very low to very high. Susceptibility to fire is also connected to vegetation type, proximity to urban areas, percentage of dead vegetation, and amount of time since the last burn. This map service represents one of seven standard input layers which support the USFS State and Private Forestry Potential Assessment Redesign Project. The data is developed for national and regional assessments. Full layer description.
• 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.
• Shared Content: Users can add information to the map in the form of a description and URL to a Web link, photo, or video. By adding keywords to the user content, the entry will become searchable using the Search functionality within the application.
