I would like to import waypoints from my Garmin GPSmap 62 into R. I have about 270 waypoints saved on the GPS unit. I can use Garmin's BaseCamp program to export them, but I would like to do this with R.
Once I plug the Garmin unit into my computer (Mac OS X) via USB, the file system I see is the following:
~ $ cd /Volumes/GARMIN/ /Volumes/GARMIN $ ls Documents Garmin autorun.inf /Volumes/GARMIN $ cd Garmin/ /Volumes/GARMIN/Garmin $ ls BirdsEye Garmintriangletm.ico gmapbmap.sum CustomMaps JPEG gmaptz.img CustomSymbols Profiles startup.txt ExtData SQL system.xml Filters Text wytopo11.img GPX fs_image.ver GarminDevice.xml gmapbmap.img /Volumes/GARMIN/Garmin $ cd GPX /Volumes/GARMIN/Garmin/GPX $ ls Archive Waypoints_12-MAY-13.gpx Waypoints_19-MAR-16.gpx Current Waypoints_13-APR-15.gpx Waypoints_20-OCT-16.gpx Nav Waypoints_13-JUN-13.gpx Waypoints_21-MAR-16.gpx Waypoints_01-MAY-14.gpx Waypoints_13-MAY-13.gpx Waypoints_21-MAY-14.gpx Waypoints_02-APR-15.gpx Waypoints_13-MAY-14.gpx Waypoints_21-OCT-16.gpx Waypoints_02-MAY-15.gpx Waypoints_14-JUN-13.gpx Waypoints_22-MAR-16.gpx Waypoints_03-APR-15.gpx Waypoints_14-MAR-16.gpx Waypoints_22-MAY-14.gpx Waypoints_03-JUN-13.gpx Waypoints_14-MAY-13.gpx Waypoints_22-OCT-16.gpx Waypoints_03-MAY-15.gpx Waypoints_14-MAY-14.gpx Waypoints_23-MAR-16.gpx Waypoints_04-MAY-14.gpx Waypoints_15-APR-15.gpx Waypoints_23-MAY-14.gpx Waypoints_05-APR-15.gpx Waypoints_15-JUN-13.gpx Waypoints_24-MAR-16.gpx Waypoints_05-JUN-13.gpx Waypoints_15-MAR-16.gpx Waypoints_24-OCT-16.gpx Waypoints_05-MAY-14.gpx Waypoints_15-MAY-14.gpx Waypoints_25-APR-15.gpx Waypoints_06-APR-15.gpx Waypoints_16-MAR-16.gpx Waypoints_25-OCT-16.gpx Waypoints_06-MAY-14.gpx Waypoints_16-MAY-13.gpx Waypoints_26-APR-15.gpx Waypoints_07-JUN-13.gpx Waypoints_16-MAY-14.gpx Waypoints_26-MAR-16.gpx Waypoints_08-APR-15.gpx Waypoints_17-JUN-13.gpx Waypoints_26-MAY-13.gpx Waypoints_08-JUN-13.gpx Waypoints_17-MAR-16.gpx Waypoints_26-OCT-16.gpx Waypoints_10-APR-15.gpx Waypoints_18-JUN-13.gpx Waypoints_27-APR-15.gpx Waypoints_10-JUN-13.gpx Waypoints_18-MAR-16.gpx Waypoints_28-APR-14.gpx Waypoints_10-MAR-16.gpx Waypoints_18-MAY-14.gpx Waypoints_29-APR-14.gpx Waypoints_11-JUN-13.gpx Waypoints_18-OCT-16.gpx Waypoints_29-APR-15.gpx Waypoints_11-MAY-13.gpx Waypoints_19-APR-15.gpx Waypoints_30-APR-14.gpx Waypoints_12-MAR-16.gpx Waypoints_19-JUN-13.gpx Waypoints_30-APR-15.gpx
Within the GPX directory, there is a
Current directory that contains Current.gpx.
I'm not sure if that is the file that contains my waypoints, but this is what I started with.
I tried to load this into R with rgdal:
> readOGR('/Volumes/GARMIN/Garmin/GPX/Current/Current.gpx', layer="track_points") OGR data source with driver: GPX Source: "/Volumes/GARMIN/Garmin/GPX/Current/Current.gpx", layer: "track_points" with 9759 features It has 26 fields
There are way more entries than waypoints that I expect to have. Also, none of the columns in the data slot of this SpatialPolygonsDataFrame have the names of the waypoints.
So, am I looking at the wrong file? Is there a better way to load the waypoints into R?
