I'm sorry if my question is stupid but I had to ask. I'm building a database of US states, cities, streets AND their basic relations to each other. I already have state and city tables. Where can I find street data to purchase? I know nothing about GIS and I'm too busy to learn it. So I have to buy it i believe. |
AFAIK currently OSM doesn't have a ready to use preprocessed dataset of that kind of information. You might want to invesigate the Nominatim internal DB structure to make use of the parsed street/city/countrie hierachies. |
Several consultancies will extract street data from OSM for you. http://wiki.openstreetmap.org/wiki/Commercial_OSM_Software_and_Services I'm working for opencagedata.com and that's a common request. http://openaddresses.io/ is a good source for the US, but expect to download 500GB of raw data to be cleaned up and processed. Personally I never managed to get a full TIGER data set downloaded, their server keeps timing out. |
Maybe you can find a solution via mapbox.com ... |
For the US, will the TIGER data give you what you need? Read the documentation linked but I think it is the Edges (Lines) National database that contains all the roads. |
