       vector map.


       vector, import, GPS

SYNOPSIS help  [-vwrtpuzk]   [output=string]    [port=string]    [--overwrite]   [--verbose]

           Verbose mode

           Download Waypoints from GPS

           Download Routes from GPS

           Download Track from GPS

           Force import of track or route data as points

           Use gardump instead of gpstrans as the download program

           Import track in 3D (gardump only)

           Do not attempt projection transform from WGS84

           Allow output files to overwrite existing files

           Port Garmin receiver is connected to
           Default: /dev/gps

DESCRIPTION  allows  the  user  to  import  waypoint, route, and track data from a locally
       connected Garmin GPS receiver via the gpstrans program by Carsten Tschach or  the  gardump
       program by Marc Hyman.


       If  the  GPS  is set up to output WGS84 Lat/Lon, 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 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 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

       Before  running, gpstrans should be set up to output WGS84 latitude-longitude,
       as follows:
       $ gpstrans -s
       datum:  100 (WGS84)
       format: 2 - lat/lon  ddd.ddddd


        db.execute,,, v.db.connect, v.patch
