[OSM-talk] The Case for Open Geo Data - resources?

[Mike N]

I map in OpenStreetMap for fun, but when it comes to talking to local 
governments or the media, I don't have a good idea of how to justify 
open data.    I'm thinking in terms of being able to tell local 
government how open Geodata would benefit them.

   Are there any resources that discuss the benefits of open Geodata or 
open transportation data (GTFS), as well as the best license - Public 
Domain?  Other License?

   Thanks,
