While I don't work in GIS myself I'm trying to support one of our users here who looks after all our mapping and GIS data. We've received a 3.2GB Tiff image containing satellite imagery of our site and I'm wanting to find a way to re-size it down a bit to make it easier to work with.
Is there any open source/free software out there that can handle this sort of file size?
I've tried Irfanview, Imagemagick, GIMP without success.
The servers I'm trying to work on have plenty of memory and disk available but perhaps not enough to fit the whole file.
Is there an easy way?
