I'll admit to not closely following the JP2 work, but I've still got a
question: Last I checked, JPEG compression was lossy. Has this changed
with JPEG2000, and if not, how do we reconcile lossy compression with
recapturing the pixel values/contents?
For instance, I have a particular interest in using WCS for sea surface
temperatures, as one example, and content rich weather radar data as
another. If we invoke a lossy compression scheme, I lose data.
Am I concerned about a solved problem?
Also: in the examples, you cite basic surface met observations data.
We already move that quite nicely via WFS, and I'm not sure that
particular example has bearing. NOW: attempting to represent fine grid
from a model where the output is the result of shading or contouring
might be an example of a utilitarian implementation. Pedantically
speaking, of course ;-)
Thanks, Gerry

Hi,
Below are comments from Ron Lake and Sean Forde responding to questions
I asked about possible relationships between the OGC GMLJP2 (GML
JPEG2000) work they are involved in and the GALEON IE. It could provide
another standards-based approach to delivering the kinds of datasets we
are working with in GALEON.
Especially I call your attention to the suggestion that we find a venue
at the Bonn OGC technical commitee meeting for further discussion. I
suggest we spend a few minutes at tomorrow's GALEON telecon on this topic.
