[GraphHopper] Indoor Navigation

[Peter K]

Is indoor data available from OSM?

You feed graphhopper with your indoor data and apply a dijkstra to it.
You could have a look into GraphStorage3D to get a feeling how you can
do it. The tricky thing is to get the correct location+height indoor
from your device. And then if you have that you'll probably need to
change the node lookup a bit (via Location2IDIndex).
