v.in.garmin allows the user to import waypoint, route, and track
data from a locally connected Garmin GPS receiver via the
program by Carsten Tschach or the
program by Marc Hyman.
If the GPS is set up to output WGS84 Lat/Lon, v.in.garmin will
attempt to automatically transform the coordinates to the current projection.
In all other cases, no checks are performed for datum, projection and format of data.
You must check for yourself that your receiver, gpstrans and GRASS
use the same map datum and projection.
The automatic transform may be skipped by using the -k flag.
Route and Track data may be uploaded as points by using the -p flag,
otherwise they will be imported as a line. You can run v.in.garmin
multiple times and merge the line and point vectors with the v.patch
command if you want, but take care when merging dissimilar attribute tables.
Future versions of GRASS will use gardump as the default download
program. It can talk to newer Garmin GPSs, while gpstrans seems to
be mostly abandoned these days and only works with older GPSs. The current
version of gardump (ver 2.5) will not yet talk to USB-only GPSs, but
you can try the v.in.gpsbabel module for those. The gardump
code has been tested with an older Garmin GPS 45 and a newer GPS V and is
expected to work with everything in between.
Before running v.in.garmin, gpstrans should be set up
to output WGS84 latitude-longitude, as follows:
$ gpstrans -s
datum: 100 (WGS84)
format: 2 - lat/lon ddd.ddddd
gardump from the "garmin-utils" package
cs2cs from PROJ.4
