This cool cideo from the Esri Mashup Challenge held at the 2010 Esri UC shared by Alta4. FlirckrCloud is a Mashup combining Photos and their tags from flickr with a world base map from ArcGIS Online
This Mashup covers every part of the world and uses dynamic queries issued by each new map positioning (pan, zoom). It is recommended that users zoom in to a medium map scale in order to get the best experience. A photo play back animation will automatically start. In case it come to an end, just slightly pan the map in order to replay the animation.
