Hi,
I'm new on the list, and new to OSM mapping, and I can't find a
definitive answer for my queries in the documentation so I thought I'd
post in here.
I have a number of potential , specific use-cases where I want to
calculate the geometry of the roads used in a route but I can't
identify if that information is easily accessible with the OSM data.
Does the OSM map data contain information such that the geometry of
road/routes could be calculated both in 2D (radius) and, to a lesser
extent 3D, and could it be incorporated into routing calculations?
Of cause it does.
It's a graph made out of nodes (with latitude and longitude)
and ways as an ordered list of such nodes.
You can apply all geometry-calculations you like.
If you are interested in writing specific metrics or routing-algorithms
without caring about the rest of the infrastructure
I suggest to look at Traveling Salesman. You can write
a new metric or algorithm as a plugin and it will be selectable
in the config-dialog.

(I'm the maintainer but haven't done anything on it in a while.
It does however work well for maps up to the size of a major city.)
