[GRASS-user] using orthortectification tool to orthorectify SPOT-5 images

[Luis Lisboa]

Greetings
I will receive a few SPOT-5 and I will need to Orthorectify them. First of
all, how can I use i.ortho.photo in WIndows (the menu entry is disabled)?
Second, does it already include a DEM product or I should download one?
If I need to download, what free DEM do you suggest?
Thanks
Luis
