Flickr used geotagged photos to generate shapefiles that include neighborhoods, and released the data into the public domain: http://code.flickr.com/blog/2008/10/30/the-shape-of-alpha/ The data is quite valuable but definitely is not perfect - depending on your needs, you may need to curate it. As another option, Urban Mapping offers a fairly rich neighborhood-oriented webservice API on a fee-per-query model. As such you won't get the polygons from it; for that you'll need to a direct licensing agreement (not sure what their pricing is on that but under low to moderate query volume the API would be more cost efficient.) See http://www.urbanmapping.com/products/urbanware/neighborhoods/ So you have the Zillow shapes, Flickr shapes, and Urban Mapping's API as the main options as far as I'm aware, each with various pros/cons. I'd be curious to hear more about your intended use case. Anyone know if the OSM folks are thinking at all about neighborhoods? -Josh W blockchalk.com
