Update: The URL is now http://www.seadragon.com/.
Update: Changes in the Microsoft services have hbroken Photozoom and Seadragon working together. The map, however, is still available at DeepZoomPix (Photozoom's new name and site). Microsoft's Silverlight is needed.
Today I wanted to take the USGS 7.5 Minute Series map of the Kingston, RI quadrangle images and allow the user to pan and zoom on the web. Within a few minutes I discovered Microsoft's Image Composite Editor, Photozoom, and Seadragon. These tools worked quickly, without error, and at almost no effort on my part. I am very impressed. I am also humbled. My industry is full of REALLY smart people.
