Tracks to Routes Confusion

Hi folks.

Can someone explain to me why there is a difference between a copied track (someone else's GPS track) and the route that BaseCamp translates it into? I'm getting major discrepancies here.

In the attached image, the green is the track I want to follow. I chose to make a route out of it (apparently that's what I need to do) and it got translated to the pink route. Quite confusing, that pink route.

Am I doing something wrong? Any insight appreciated.

Cheers
  • How can I just assume the track I want to translate, into a route? This translation is having me running in circles. The algorithm isn't so good.

  • Have a look to Settings -> Routing

    On the bottom right you can select how many stopovers (don't know right word cause I'm German ;)) you'd like to have.
    I selected 200 and everything works perfectly.

    Just check how many stopovers your device can handle.
  • Sorry to be ignorant but if someone has sent you a track and you want to follow it why are you trying to turn it into a route? Just transfer the track to your device and follow that :confused:
  • Tracks define your path. Tracks are recorded waypoints (coordinates) after a certain distance or time, usually distance. Depending on memory you can record an unlimited number of points. Tracks are not as efficient as routes for storage but they don't require a map and roads to function. Routes can be as simple as a start and end point. BaseCamp and your GPS use map information to calculate a route. When you convert a track to a route, BC inserts enough waypoints onto the track such that hopefully when the route is calculated through the inserted waypoints you get a route that follows the tracks. If there is no road or trail to follow on the map you probable get straight lines unless BC is smart enough to insert a bunch of waypoints when no roads are available.
  • And as I understand it that is the OPs problem, he wants to follow the track and in converting it to a route BC is using whatever it's set at and the map that's selected, but I'd be surprised if he will ever be able to get the 'route' to match the 'track'. My suggestion is he sticks with the track :)

    Many current Garmin units don't support tracks for following. The OP didn't specify the procedure he used for conversion. In the Mac version of BaseCamp (not sure about Windows) there's a menu choice under "Edit" that automatically creates a route from a track. It basically creates a via point for each track point and then routes. If the OP has not checked any avoidances that would cause the route to deviate, it should follow the track exactly. It's best to keep the point count below 500 for most units, as little as 200 for some.

    I've used this process many times to convert tracks to routes and as long as the track follows a routable road, the resulting route matches it exactly. An attached copy of the track file and a summary of the relevant BaseCamp settings would be helpful.
  • Agreed, but I believe from the OPs other posts he's using a handheld (Garmin 62) that does support tracks. I get the impression he's a biker and therefore suspect the map won't route him correctly whatever he does, but I've been wrong before :rolleyes:

    As you say, a copy of the track file might help.

    OK, here's a rundown. Let me clear some things up.

    I am indeed a cyclist using a 62. I found some tracks online posted by other users. I am assuming they are tried tracks that are obeying all the safety rules and optimized for the area, etc. I am giving them more of a vote than what the 62 would know about. Why? I don't know.

    So I wanted to try to translate tracks directly into routes, as I can only follow a route, not a track.

    Yesterday I was out for a full day. The 62 had me onto streets that were not even there. It had me going into industrial zones that wouldn't allow me in (security), as well as superhighways where I know for a fact it's illegal to be on a bicycle, not to mention very unsafe. It was quite messed up.

    Ultimately, I'm trying to find the best way for a cyclist to get from A to B.

    Cheers
  • That's what I suspected. Unfortunately unless you can establish what maps, with what routing capability etc etc these tracks were from I don't believe BC will be able to accurately turn them into a route. It *might* work if you select direct routing in BC and use the track to route conversion in BC mentioned above :confused:

    Alternatively I know cyclists who simply download 'tracks' and follow them ;)

    OK, then perhaps that's what I want. How can I actively follow a track? I thought the follow tools were only in routes.
