Indoor routing using Graphhopper

votes

I am new to Graphhopper, I am building indoor routing.

Currently everything worked fine in a floor.

I was wondering how to use graphhopper to navigate/routing between floors?

I know that Graphhopper support elevation, can I use it?

Can someone give me advice.

Thanks

What is so special about routing between floors? As long as there is a connection between the floors it will be exactly the same like regular routing. - scai
AFAIK no routing engine has support for indoor details, but please consult wiki.openstreetmap.org/wiki/Indoor - MaM
@scai you are right, there is nothing special from a data structure point of view - Karussell
@sharon I don't understand which problems you are facing. Did you already tried it? The only problem is the data format, where there is no default importer. But I'm not aware of a standard format for indoor .. - Karussell

In my opinion, the only issue might be getting the nearest node from the routing networking for start / end points.

Given a latitude, longitude and floor, I don't think Graphhopper can, without a few modifications, limit its query process to a specific floor (OSM's level tag).

I think it's a different concern from elevation. Would appreciate Karussell's opinion, that subject interests me too.
