Value of OpenStreetMap as a free database

There's plenty of examples of open government datasets that could be imported into OpenStreetMap, but not all of these turned out to be mutually beneficial for the parties involved. We've collected the following case studies where local government collaborated with OpenStreetMap to both sides' benefit:

Case studies

Policy integration of open data (West Midlands Combined Authority, UK)

Collaboration between local transit agency and OSM community (Milan, Italy)

Automatization of updating curb situation (Seattle, WA, U.S.)

Immediate value of crowdsourced data (Chennai, India)
