Layers
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.
