Question

I’m trying to develop a application that uses informations from google/bing maps, but I need the vertice data to recreate roads and I can’t use images since I can’t get road names and height info.

I need vertices/nodes of streets (with latitude,longitude,altitude, street name ) and no visual data.

Thanks.

Open Street Map is definitely the way to go for this – extracting vertex information from Bing/Google is both technically difficult, and a breach of the Terms of Use. OSM data is better quality in many cases and, more to the point, free to use under a CC-BY-SA licence.

You’ll also probably need a spatial database in which to store the information. I’ve written a couple of articles about loading OSM data into SQL Server which you might find helpful. e.g.:
