Re: [GRASS-user] Landsat Stack import and export
Greetings Regarding the possibility of exporting an GROUp, using r.in.gldal, the groups are not listed in that menu. So the user cannot see the available groups. It's still processing but IO have one question: The processing bar restarted at least 3 times, what is happening? Because it file, now, it seems that it's not growing. Is it doing some file-check or something?

Is it possible using GRASS? To my knowledge no. Sure it is. Create a group in GRASS, export the group (r.out.gdal input=group_name) to a file format that supports multiple bands, e.g. GeoTIFF.

So the user cannot see the available groups. g.list type=group will list all groups It's still processing but IO have one question: The processing bar restarted at least 3 times, what is happening? If you export a group, each raster map is exported separately, even if they all end up in one file. If you use r.out.gdal --verbose, there would be several messages like Exporting raster map raster_name (band number)... and for each, the progress bar starts anew. Because it file, now, it seems that it's not growing. Is it doing some file-check or something? Depending on the grass version you are using, there might be some checks first to prevent potential data loss (latest 6.4+). Note that r.out.gdal uses the current computational region (resolution and extends) for export.

The import is easy using r.in.gdal but my difficulty is to export 6 bands in one single file. Is it possible using GRASS? To my knowledge no. But you can export it separately, then merge with GDAL tools. See http://gfoss.blogspot.com/2008/06/gdal-raster-data-tips-and-tricks.html - Merge various map/bands into a RGB composite (should work for more bands than 3).
