Where can I download OpenStreetMap data by geographic region?

Question

I want to use OpenStreetMap data for an ArcEngine application I'm working on, and I need the data to be stored locally. I don't want to download the entire planet.osm file, but rather by state, county, region, etc. Are there any resources where I can download OSM data by geographical region?

Answer 1

Portions of OSM data consisting of a specific geographic area are called Extracts.

Extracts within the USA are only available by states and a few metropolitan areas. . These are often updated daily (unlike cloudmade, which hasn't updated theirs since December!)

If you want something more specific like a county or a municipal boundary), you can download the appropriate state extract and then use a tool like osmosis to filter out all data within a specific area to create your own 'extract'.
