GPS Drawing Tracks for Google Earth
Here are the KML track logs from the five GPS I collected last Wednesday. These will load directly into Google Earth.
GPSBabel was used to extract these track logs from the GPS's with this command:
gpsbabel -t -i garmin -f /dev/cu.KeySerial1 -o kml -F ~/Desktop/CTIN405/gps_6.kml
-t instructs GPSBabel to extract the tracklog only
-i specifies that the input device is a Garmin
-f specifies the input "file" — in this case the device is actually the Keyspan serial adapter connected to my Macintosh — your precise device will almost certainly be different, depending on your computer, operating system, and how you connect the Garmin device to your computer
-o indicates that the output type, in this case a Google Earth KML file
-F specifies where I want the output file saved
On my computer I had to run this as a privileged (root) user in order to access the device.
