Large images on the Web

Giving a public access to gigapixel images requires that you have a way to make them accessible through the web.

There are quite a few technologies that allow this, here are the ones I know about:

1. The Google Maps API, written in Javascript + DHTML
2. Google Earth, a standalone application using HTTP to retrieve tiles.
3. Zoomify, written in Flash
4. FSI viewer, also written in Flash I think.

With these technologies, a few very large images can be viewed on your browser:

1. The Earth, on Google Maps, using a mix of satellite images and maps
   
2. The Blue Marble Next Generation Dataset from NASA on Yawah (resolution is 500 meters/pixel, so the complete image is about 86400x43200 pixels)
3. Digital photography, such as
• xRez (stitching a large array of digital images)
• The Gigapxl Project (scanning a very large format argentic film)
  
• Hal9000 Ikonos (stitching a large array of digital images)
  
• Scott Howard (Machu Picchu and Sydney By Night) (stitching a large array of digital images)

Other sites provide information on very large images, but do not make them available to the public:

• Max Lyons (who was the first to break the Gigapixel barrier for stitched digital images)
  

If you know other sites providing very large images, please comment.
