@Bart-DM We mostly start by genarting a gpx-track which we import (from a magazine, a track genarator (MRA, Kurviger, TomTom etc).
This is than converted to a route on OSM. We check the route against HERE and TomTom and add points to make the route 100% same for all systems. Now you
In this example I used the function Increase points to test that. It is a bit much, I agree.
But it may be oldschool, but after every turn we place a viapoint to make sure that even someone who has selected something else as fastest of shortest as his favorite routecalculation, go the way we planned. That requires some more points to be on the safe side.
TomTom has the behaviour to cut corners in villages (riding through living area's) whereas Garmin uses the crossing in center-village to make the turn.
We had compliments from users that the routes are not different anymore. So that works.
Exporting the track would mean I have to import it again. A track does not show the must-visit/hard points or does it?
