1. GRASS needs Project4 installation for communicating with GPS
Pl help with step by step installation procedure
see the INSTALL file which comes with PROJ4.
you need to ask on the PROJ users' list with specific problems for help.
2. Succeeded in using GPSDRIVE, with GPS, but it uses small scanned
maps of a particular resolution, with a disclaimer, not to use for
navigation.
that means "don't sue us if you get lost, crash, die, ...". The software
is suitable as an "aid to navigation" only, the authors will not
endorse it as a primary means of navigation. "This program is
distributed in the hope that it will be useful, but WITHOUT ANY
WARRANTY; without even the implied warranty of MERCHANTABILITY or
FITNESS FOR A PARTICULAR PURPOSE." --The GPL
3. Suggest any software that Imports GRASS data, or shape files..
Maybe easier to export data FROM grass to a common format which the
other software can read. Many are supported.
4. Qgis for Linux also has lots of hassles.
Pl help with step by step installation procedure
see the INSTALL file which comes with QGIS.
