Hi Landon,
It has been an interesting discussion, algorithms copyrights, most used
formats, limitations, internal details, etc. I definitely agree that it got out
of control and we should end some place but I and going to give you a quick
answer.
> What are the limitations of Geotiff/JPEG com
That is great. Thanks!

But you can't compress data types other than byte in JPG. Can you do that in
JP2K?

Bob,
Sorry to mess with discussion but if someone is suggesting the use of Geotiff
with JPEG compressed as a "Open File Format" (copied and pasted from

All,
Can someone remind me again, are we talking about saving spa
data than meet the eye, and that usually doesn't come in
unsigned integer 8 bits. :)

So hung up on wavelets, we are.
Internally tiled TIFF with JPEG compression and similarly formatted
internal overviews can achieve 10:1 compression rates without

Not a stupid question -- but it doesn't work that way. The artifacts
are due to the wavelet processing of the pixels nea
