Hi,
Please help me

  1. Interface Garmin Etrex GPS with GRASS for
    a. on line usage as well as
    b. ‘after survey’ data of way points and track download.

Earlier I received mail from this list, that PROJ4 is preloaded with GRASS6.1…
Then why it gives eerror about not finding modules of PROJ4…

Is there a bug…
Thanks in anticipation

I have started to write 'v.in.gpsbabel' (using http://gpsbabel.sf.net) but
don't have the time to complete it. Volunteers?

No bug, that answer was wrong. GRASS 6 supports and needs, but does not
contain PROJ4.
You have to get it as extra package.

you should try to use Qgis...
there is a plugin for downloading and uploading from garmin...
youn can be also interested in gpx2shp ...
http://gpx2shp.sourceforge.jp/
it is a simple tool for converting garmin data to shp files...

I hope this help...

Within GRASS the only [published] realtime GPS software is my
m.realtime_gps for GRASS 5.3. Uses gpsd.

You may be better off using software like gpsdrive for this task.
You can export a GeoTIFF + shapefile from GRASS for a backdrop image??

b. 'after survey' data of way points and track download.

Use v.in.garmin or QGIS's GPS plugin.

PROJ4..

It isn't preloaded, but it is a prerequisite. You need to have the cs2cs
program installed to use v.in.garmin, not just libproj. Some installs of
proj may only provide the library, not the executables. Most have both.

Is there a bug..

Perhaps.. I have just updated this test in CVS:

CS2CS=`which cs2cs`
if [ "$CS2CS" = "" ] ; then
    echo "cs2cs program not found, install it first"

Which should have stopped things if cs2cs wasn't found.
