We are gathering the GPS-coordinates of every speed-limit sign on earth. You don't need a GPS device, just 2 minutes of your time. Its open source so you can contribute.
People can put these data into GPS devices to regulate or warn of excessive speed. Google, Garmin, Teleatlas, even AAA aren't doing this, so please help out. Plus the sign you capture is copyrighted with your name since you found it. CC license also supported.
