Thanks Jesse, I'll be happy to help test this when you're ready.

Subject: Re: [udig-devel] Problem using GeoTIFF file in uDIG
Hi Bob,
We are currently moving a branch of uDig to use Geotools trunk which has
a wicked implementation of Geotiff. It can render GB+ sized Geotiffs
very efficiently as long as the overviews are generated. I also think
there is some JPEG2000 support somewhere on trunk. However it will be a
little while before it is completely stable. But if you have the
patience, helping us test it would really be great.
You've been a great help already. I'll let you know when a Milestone
from the branch comes out.

Hi Jesse:
thanks for that pointer, it fixed my problem and
I was able to display GeoTIFF files with the Mantario Trail SHAPE file
superimposed upon them. I currently have 6 6Mb GeoTIFF files shown.
I tried translating one of our MrSID images into GeoTIFF to
display much more of the trail, but the GeoTIFF ended up being 600Mb and
uDig couldn't seem to handle that. It would be a lot better if uDig
supported MrSID files which we release a lot of our imagery on the MLI
here in Manitoba in. Or else if you can't support MrSID because of
proprietary issues conflicting with the LGPL license then at least if
you supported JPEG2000 would be an option. I couldn't translate this
file into ECW because of a GDAL 500k ECW SDK issue and anyway uDig
doesn't support ECW.

This is a frusterating problem that I have not been able to
solve. It seems that sometimes it works and sometimes it doesn't. I
found a hack that works though. in the short cut add:
-vmargs -Dosgi.parentClassloader=ext
that worked for me. I will update the install script.

I am trying to include 6 GeoTIFF files in my uDig

the GeoTIFF category is:

So I listed the information about one of the images
