Image Extraction from CD's

Good Afternoon

I'm interested to know how folks are importing spot images into Grass if these
images are not on tape.

I have been simply copying these image files into a cell directory in my
MAPSET directory and then viewing them with the help of r.support as raster
files.

I run into difficulties however when trying to reference the images.

While using d.what.rast I find that the areas I am interested in on the image
do not correspond with those on my hard copy map. Even though the region
I specify ( UTM zone 14) is correct.

Any suggestions as to how I can correctly read these images in ? The tutorial
gives information on Tape Extraction but nothing else.

Thank you

Jeremy

Wang Song developed a script to extract SPOT imagery from CD. Wang has
left CAST but I think that Rob Dzur (rob@cast.uark.edu) may be able to
track down the scripts....
