I suspect the immediate problem is the extra+outdated GDAL version in /usr/local/. It would be strange if a newer version of the GDAL ubuntu package were depending on an older version of GEOS, right? In addition, I don't see GEOS 3.1.1 available in any of the recent ubuntu versions, so suspect the /usr/local/ custom installed version is to blame for the bulk of the trouble. http://packages.ubuntu.com/search?keywords=libgeos You can use "ldd" on the libraries found with: $ locate libgdal | grep '\.so' to verify which one(s) are looking for libgeos 3.1.1. e.g. $ ldd /usr/lib/libgdal.so.1 | grep geos $ ldd /usr/lib/grass64/lib/libgdal.so | grep geos Hamish ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

I doubt that r.info has a problem reading the metadata that pertain to a queried raster map. If I am not wrong, it merely reads simple text files that reside inside the "hist" directory inside the corresponding Mapset. My guess is that you use an older version of i.landsat.toar whicj, indeed, produces empty raster maps. Unfortunately, I do not use (nor have any access to a Windows machine) so as to be in position to help directly. We need feedback from someone with a Windows OS. ( On/Off-Topic: is there a way to run and test GRASS in an emulated Windows environment for those who don't have a legally licensed Windows OS? ) Best, Nikos ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
