If you can describe very precisely what your inputs and outputs are (when you say "garmin" do you really mean some specific model serially or mapsource or what?) and a sample of the inputs you're using and the output file formats you're expecting, I suspect we can do it with GPSBabel, even if it requires a custom version of it or external processing or something. You can find this option in the menu on the left. Note the bearing: Rotate the plotter centre so the blue arrows align with chart North and read off the bearing of the first leg (here it is 296T). Then, follow this up by clicking on Add Layer. Begin plotting: Draw the first leg on the printed chart using a 2B pencil (it should be easy to rub off afterwards) and mark the start and end with the waypoint symbol. Click on it to pull up a new map that should be centered on your current location. Next, in the top-left corner of the screen, click on the menu icon and look for Create new map. Routes typically max out at a few scores of such points.ĭepending on the model of Garmin you have, when you captured the waypoints, it should have recorded the altitude. The first thing you’ll need to do is sign in to My Maps. Tracks typically max out at a few thousand such points.Ī route is about halfway between the two: it's a sequenced set of waypoints but without the precise intervening data. How you got there isn't recorded.Ī track is the list of breadcrumbs (which you can think of as timestamped, ordered sequence of unnamed waypoints) which would show the exact path you took to get there. There are lots of excuses involved in what you're asking.Ī list of waypoints doesn't naturally convert to what one normally thinks of as a track very well.Ī list of waypoints is what you get if you navigate to a couple of spots and click "mark".
