What about setting up a (openSource) tool set specifically for handling
Raster images for pre-processing purposes. Might even be something that
publishers could re-distribute with their datasets, as in this processor
stack works with our data.

Markus,
What's the standard (OGC?) part of this, just the calling structure, and
consequent responses? It looks like anything can be on the backenda s the

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
noticeable image quality reductions, and as an added bonus can be
decompressed a heck of a lot faster than wavelet-based formats. The
