indoorequal + Valhalla

[chrstnbwnkl]

Hi! 👋

I have recently (in the past year or so) worked on improving the indoor routing capabilities of the Valhalla routing engine. It's not fully mature at this point, because OSM indoor tagging is messy, and my use case was related to proprietary data that we were able to control more tightly.

Anyway, in order to advance the indoor routing features, I think it would be great to have a frontend that lets the user play around with indoor routes. We already have a public Valhalla instance hosted at valhalla1.openstreetmap.de/, and a web app that can be used to interact with that instance at valhalla.openstreetmap.de/. What we don't have is the vector tile visualization to make sense of indoor, especially multi-level routes.

That's why I think indoorequal seems like the missing piece of the puzzle! I would love if we could somehow bring indoorequal and Valhalla together, but I'm not sure yet how 😄 I see you are hosting a global instance of MVT as well as frontend that goes along with it. One idea would be to integrate indoorequal tiles in the Valhalla web app, where we would just need to add indoor tiles as another layer plus controls to switch levels. Another alternative would be to somehow integrate routing into indoorequal, but that may seem like more work, since it's just a plain viewer at the moment?

Anyway, I'm just thinking out loud and would love to find a way to bring the projects together somehow 😃

Hi,
I would love adding routing capabilities to indoor=.
Both solutions (you integrate vector tiles / I integrate valhalla) sound goods to improve both service.
I will take a look at your API and see what I can build with it.

Hi, I worked a little bit to see what is possible.
First it works !
recording.webm

The routing can take elevator or steps, which is pretty cool (is there is any option to force elevators ?).

The indoor= UI is not yet ready.

On the valhalla side, the API doesn't give enough information about the level. It makes the UI quite hard to understand.

Would like a test version to play with it?
