[mapserver-users] OT: Street Data Nomenclature

[.d.z.a.]

A bit off topic - I've been trying to locate some street mapping data for
London New York and Sanfrancisco with street names and block allocations and
preferably building names and am having no luck.

Is ther a special name given to this type of data that I should be searching
for or will I be forced to pay for this ( am working  on a non-profit arts
project...)

cheers.
