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.
