Distance calculations

[rasmusfr]

Hi,

My main motivation for using motis is for its fast routing (A to B) but I want the distances of these routes (with all/any transport modes). Since only the direct mode routes come with distances inherently, I have initially resorted to calculating (geodesic) distances from the polyline data. This works alright for a number of things but it seems a bit hacky and it doesn't generalize to all transport modes. For instance, for ferries I only get straight lines when doing this. I know the ferry routes are available but I am pretty clueless on how to access them or if this is even the best way of getting distances.

Ideally, the distance calculation should be one-fits-all. Are there any suggestions on what the best approach is?

Best,
Rasmus

I know the ferry routes are available

Where?

[felixguendling]

Those are in OSM and show up because of the map style but they are currently not available programatically.

Ah ok, makes sense. Thanks! As a first approximation, the straight lines are fine for my purposes for now but it would be nice to have more detailed polylines for ferries as well :) Any thoughts on the best approach to distance calculations in motis, in general?

[felixguendling]

I think we could probably just set the distance field on public transport legs as well, not just walking etc

And then we get back to the shape generating issue...

Regarding ferry data: Let's hope that Entur's FerryGateway schedule data will make the data available, including shapes. 🤞
