The best starting point is [http://wiki.openstreetmap.org/wiki/Planet Planet.osm], a snapshot of the OpenStreetMap database. It is in XML format. Data is available for the whole world and is updated regularly. Smaller extracts for certain countries and parts of the world are also available.
You can write programs and scripts quite easily to extract what you need or you can use some of the tools and procedures developed by the OpenStreetMap community.
=== Is OpenStreetMap data free? ===
There two restrictions, some call them freedoms, on '''how''' you use the data. We have a separate section on our [[License]].
* '''Attribution'''.
* '''Share-Alike'''. We would like more data to be made publicly and freely available. This depends on what license is used. Right now, we use CC-BY-SA, (see [License] for explanation). If you improve our data and want to distribute the new data, it must be done under the same license. If you make a map from our data, whether you use other data or not, you must publish under the same license. Under our proposed new ODbL license, (see [License] for explanation), the rule for publishing improved data is the same. If you make a map, you are free to publish that under whatever license you like, provided that if you have improved our data to make it, then you need to share that data (the data, not the map).
