“Now Google Maps, and my Navman SatNav have a typo in the name of the street in which I live, and so on reaching home I checked the OpenStreetMap site to see if they had got it right. Initially I was disappointed to find that, although my street was on the map, it and a number of other local roads weren’t named. And then I realised that this was my opportunity to use my lunchtime walks to make a small contribution to the common effort. The next lunchtime found me setting off with a screen print of OpenStreetMap.org, a pen and a GPS receiver.”
