Hey, Jody's running ahead with solutions but I don't yet understand what your issue is. You say the coordinates are NE which presumably means northing and easting which sounds perfect for a UTM. Long/Lat would be wrong. UDig is showing your CRS is WGS84 which is what your output also claims
What are you getting and what are you expecting? --adrian On Thu, 2007-11-22 at 10:31 -0800, Hugh Jennings wrote: > Hi, > > Just want to know if this is a known problem or an incompatibility with > some other software we use. > > 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.
