<div>Greetings</div><div>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)?</div><div>Second, does it already include a DEM product or I should download one? </div>
<div>If I need to download, what free DEM do you suggest?</div><div>Thanks</div><div>Luis</div>
