One of our favorite collaborative open data projects is [OpenStreetMap](http://www.openstreetmap.org). We’ve [talked before](http://www.pbs.org/idealab/2010/10/openstreetmaps-audacious-goal-free-open-map-of-the-world288.html) about the project’s goals, how its free and open nature is advantageous for non-profit and commercial applications alike, and how its open and near-real-time editing process is a major [advantage in rapidly changing situations](http://www.pbs.org/idealab/2010/12/how-openstreetmap-helps-to-curb-haitis-cholera-epidemic342.html), from city construction projects to natural disasters.

In our [previous posts](http://www.pbs.org/idealab/2010/08/tilemill-custom-maps-to-help-with-data-dumps-hyper-local215.html) on [TileMill](http://mapbox.com/tools/tilemill), we’ve focused on how [open data can be used to create custom maps](http://www.pbs.org/idealab/2010/09/open-data-custom-maps-better-afghan-election-monitoring259.html)and [tell unique stories](http://www.pbs.org/idealab/2010/08/helping-dc-drinkers-and-bikers-with-custom-maps230.html). One question we run into a lot is, “Where does open data come from?” One exciting source is a global mapping project called [OpenStreetMap](http://www.openstreetmap.org/) (OSM).
