[GRASS-dev] GRASS71 development packages for Ubuntu 13.10 and 14.04
GRASS71 binaries at launchpad's grass/grass-devel is only for Ubuntu 12.04.1. Any chance to get one for 13.10 and 14.04. Maybe from other repo? -- cheers, maning -- "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
[GRASS-dev] qct file format
Hi, I have several topomaps in qct format anybody who knows how to get them into GRASS? -- cheers, maning -- "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev

I created a new vector without the -v switch and it looks ok now. cheers, maning -- |-|--| | __.-._ |"Ohhh. Great warrior.
