The Internet’s Largest Image Online - 86400 x 43200 pixels!

IIPimage is a client-server system for the remote viewing of ultra-high resolution images over the internet using multi-resolution tiled TIFF images. We last mentioned it back in November 2005, they have had a few more updates since then.
Their demo of NASA’s incredible ultra high resolution Marble Earth image at 86400 x 43200 pixels is probably the biggest single image ever made available online!

Actually, it’s probably only about the 10,000th largest image online. There are thousands of considerably larger ones from dozens of companies.

Yes, that story was more a result of hype and coolness factor, rather than truly being about the largest image.
I noticed a couple of interesting images at the link you provided. What formats/systems are you using to store and allow viewing of these images?

Currently, Zoomify (www.zoomify.com). They and we both worked on an IIP-based image server at MGI Software a few years back, and also use JPEG tiles. We’re soon transitioning to our own image server, since the medical industry has some specific needs; at that time, we’ll have a new large-image format. We’re also
developing DICOM storage and communication standards for whole-slide images such as you saw.

That sounds interesting.
I think DICOM supports all major standards like JPEG, Jpeg-LS and Jpeg-2000, but medical industry hates lossy compression, so are jpeg and lossy jp2 will be out of picture, or are they still used?
As far as I know, IIP uses tiles (pyramidal tiffs?). Can jpeg2000’s progressive features help in such zoomify type applications or are tiles an easier/better way to go?
