[Routing] Help with routing using Open Street Ma p Data ‏

[Hammad]

Hello Craig,

Have you seen this http://osmparser.codeplex.com/
This osm parser parses the osm data as you want and saves it in spatialite
from where you can export the data. You can generate routing in spatialite
as well to test the routing.

Regards,
Hamad

Hi Craig,

I think you don't have to parse OSM data. There are parsers already doing
that to create suitable data structures for routing. Afterwards, you can
customize your routing needs, either by changing rules, weights, etc. It
will depend on the platform you choose.

You can start by reading http://wiki.openstreetmap.org/wiki/Routing

If no one is suitable for you... came back to the list :-)

Regards,

Jorge
