Thanks for the ideas, Agustin, but I didn't understand topic 2. Could you explain more? I've actually liked the VRT plugin idea. I'm going to learn a little about gdal's VRT and see what I can do with it. As far as I know, VRT is kind of tricky for me... Too many different sintaxes for different things. But I'm going to try to sort it out. Glad to see it worked. Are you a ubuntu user? If not, in what system did you test? Maurício de Paulo
