OpenStreetMap is a fabulously ambitious project to map the world and provide it for free to everyone under Creative Commons and open source licences. This is especially important when you remember that sources like Google and Nokia maps are proprietary and have restrictive licenses which prevent unlimited use.

The astonishing thing is just how far they’ve got, from a cursory glance it looks as though most of the major parts of the world are already covered, and from the looks of it, they’re moving into Africa in a big way right now. Check out the wiki if you want to get involved in the process. This is exactly what the Internet does best, and it’s a superb example of real user generated content (as opposed to that fake stuff which companies encourage for their own profit).
