HI all,
I am working on various roadtypes, so I am gathering data for that.
One of my friend told me that centerline maps are the best source for
this. but I have no idea how centerline maps looks like, how to get
them, if so how to maps them onto shape files. can anybody refer me to
any good source of data about centerline maps.

thank you,
shashi.
