Allow Scenic to jump road breaks
Quote from BikerMike on 17.04.2023, 03:07On the twisty back roads in Australia from time to time I find favourite roads have a short break in them due to issues with the mapping. Where a road is continuous the map may show the road stopping and starting again with a discontinuous (no road) section of less than 10 meters. I know the road exists as I ride these no road sections regularly. This clearly is a problem with the map supplier and really screws up navigation. It would be a great feature if two way points were say less than 20 meters apart and there was no road if scenic could assume this is a mapping issue. Scenic would allow way points where there is no road so this distance could even be less with a waypoint in the no road section.

Theoretically there are two ways to resolve these issues:
- Make two routes and join them. This is possible theoretically, but this would mess up distance and time to destination values. In essence, Scenic would have to load the first route until the gap, and then switch to the second route after the gap. Honestly this is not something I want to implement as it would make navigation code hugely complicated and error prone. It would be a terrible workaround for a bug that should be resolved in the map data.
- Use a different 'straight line' routing mode for the section of the route where the gap is. However, Scenic uses the HERE map framework and routing algorithm, and this only supports one routing mode per route. HERE might add the possibility for more routing modes per route in the future. Once they do I could add this, and this would be a much cleaner solution.
At this moment your best bet is to report these map data issues directly to HERE. HERE updates their maps very frequently, so chances are this will be fixed soon. There are two ways to report map error to HERE: https://scenic.app/help/roads-not-on-the-map-errors-in-the-map-data/
Hope this helps/explains. If not, or if you have other questions, please let me know. Happy to help.
Best regards and ride safe,

Another point is:
What will you do when there is a broken bridge, like we actually have in Germany. Ahrtal.
Complete calculation will be messed up when you say: Its just 10 meters, so ignore it.
I understand your point, BikerMike. In many cases it wouldnt help to ignore the map.
Guido‘s hint to do just 2 routes should solve it best.
