Description

I can display geotiff's we have created but the geotiff tags don't seem to be read completely.

The image is in WGS UTM Zone 39. Below is the result from listgeo

Originally a uDig bug so ON CLOSING:

1) the example should be tested against a uDig with a fixed geotools

2) Mr. Hugh Jennings <hugh -- a t -- photosat.ca> should be notified ( perhaps he's on the cc list, I can't tell.)

tested the sample images with trunk, seems to be working fine.
