How to match a ferry route #16

Open ratrun opened 9 years ago

ratrun commented 9 years ago

Some of my test tracks include ferry rides. Here the algorithm often fails as ferries don't always take exactly the same route. The algorithm could maybe adjust the gpxAccuracy in this case to a much more relaxed value, eventually by somehow takeing the length of the ferry route edge into account. Besides that the algorithm works pretty well.

Thanks! Yes, that is tough. I'll think about it.
