I have a new hobby: fighting the monopoly of GPS navigation map vendors Navteq and TeleAtlas.
“OpenStreetMap creates and provides free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways. “
If you have a GPS device, you will know that the maps of your home town are probably not too accurate. It sometimes takes years before a new roundabout is included in a map update.
Now, in the same fashion wikipedia works, here’s your chance to help: let your GPS device track your way to work, export the data as GPX, and upload on openstreetmap.org. Then go into the editor and start adding as much detail as you can. Invite all your friends (they don’t have to own a GPS – they can add detail to your maps anyway).
