v.out.gpsbabel(1)

NAME
v.out.gpsbabel

DESCRIPTION
v.out.gpsbabel allows the user to export waypoint, route, and track data from a vector map into a locally connected GPS receiver or as a file in many common GPS data formats. Translation is done via the GpsBabel program.

Do not use 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. See the GNU General Public License (GPL) for more details.

NOTES
v.out.gpsbabel automatically reprojects data from the projection settings of the current location to Lat/Lon WGS84.

GPX format is used for data interchange between GRASS and GpsBabel. If the requested output is GPX, then gpsbabel is never run.

OGR's GPX driver knows a number of standard field names. If an attribute column matches the name it will be used in that field. Otherwise the attribute will be placed within the metadata section of the record. Not all fields names are used with all feature types (e.g. DOP fix error is not meaningful for route lines). You can use the v.db.renamecol module to rename columns.

These are the standard GPX data fields known to OGR:
ageofdgpsdata
cmt:     Comment
course
desc
dgpsid:     DGPS station type
ele:     Elevation
fix
geoidheight
hdop:     Horizontal dillution of precision (estimated fix error)
magvar:     Magnetic variation
name
number
pdop:     Positional dillution of precision (estimated fix error)
route_fid
route_point_id
sat
speed
src
sym
time
track_fid
track_seg_id
track_seg_point_id
type
url
urlname
vdop:     Vertical dillution of precision (estimated fix error)

EXAMPLES

  GPX Export
Export a vector lines map to a GPX track file:
v.out.gpsbabel -t input=trail output=trail.gpx

  GPS device connected via USB adapter
Export vector maps named waypoints, tracks, routes to a Garmin GPS connected to /dev/ttyUSB0:
v.out.gpsbabel -w input=waypoints format=garmin output=/dev/ttyUSB0
v.out.gpsbabel -t input=tracks format=garmin output=/dev/ttyUSB0
v.out.gpsbabel -r input=routes format=garmin output=/dev/ttyUSB0
