Is it possible to add a 'level' info?

[lmdc45]

for instance I would have

• ground level:0
• bridge:1
• Underground:-1

At this stage I got small issues with some path going from under the bridge straight to the bridge, as lines are crossing...

I am trying to eliminate common/near vertexes on these locations as a way to solve it, however was wondering if it would be possible another way.

Thanks

Hi, it would definitely be interesting to incorporate something like this, but at the moment there is no support: all vertices that are sufficiently close will be considered as a node in the graph.

I think changing this would only need to affect the topology.js function, which is responsible for turning the LineStrings into nodes and edges.

Ok thanks.
I am not an expert so will try not to touch topology.js.
I will try to work on the geojson data first, to avoid close nodes in intersection if different levels.

In fact this seems quite similar to issue #25 , will look at adding z coords
