Ok, here is a little description of what I try to achieve:
We have a satellite image in black and white, which show IR brightness
temperatures. The data is scaled between 0 and 255 for viewing, and this is
packed in a geotiff file
Now some users would like to have the true value of the brightness temperature
embedded in the file also.
But unfortunately it doesn't seem possible to do with geotiff...
Thanks for your help.
PS: we are about to switch to gdal 1.6.
