I have a large ortho image, that is in MrSID format (A full county at high res). The file is ~3.5 gig. It covers a much larger area then I need. So I set my region to the size that I do need, and then imported. The import took something like 10 hrs. And, I now see that in my PERMANENT folder I have 3 files that are each 15 gig (one red, one blue, one green), The map was imported, but if I zoom to the size of the current map, it seems that the whole map was imported, not just the area inside the current region. I thought that imports are cropped to the current region? Am I mistaken about this? Is there some setting to cause this to happen?
I did the import with r.in.gdal. I am using the binary release of 6.4 on a Mac. The reasons that I care are 1) This map, for a small area of interest, it taking up 45 gig on my hard drive. 2) Because the map is so large, it takes a while for the display to update when I make any changes. Any guidance? Thanks, --Adam _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
