I was hoping to get a better error message or warning :-)
My understanding is that the image is showing up with data in the
range of 752107, 2590533 (from the screen snap); but poor uDig
still thinks the map is in WGS 84 (so the output is invalid).
Indeed it looks resampling is not happening; the image is just
being dumped onto the screen (which is fine when the map is changed
to the right projection...).
Jody is correct here. I expected to see coordinates in lat long or
a coord system of wgs84 UTM zone 39n. when I load it in.
In addition I have noticed that the distance tool gives
understandable results once I have set the projection to UTM. Before
this any attempt to measure a distance come back with no result.
With version 1.2_trunk I get an error message on the map window
"Unable to calculate the distance".
Should this tool normally give a "distance" in decimal degrees or is
it intended for no measurements to be given when displaying an
unprojected dataset?
Finally, if you would like I will put together a smaller version of
this image with the same geotiff tags for you to test against.
