I'm in the process of importing Routing data from the OpenStreetMapData shape files into SQL Server 2008 R2, my purpose is to enable routing, so my question is which Shape files are critical to routing? ( I will be overlaying on the WorldMapData (so I have most of the basics covered already).
Can I get away with just roads, or do I need to add other shapefiles in order to get routing to work?
The shapefiles include:
adminareas
roads
buildings
places
pofw
pois
power
powerlines
railways
etc.
THANKS!!
