We went on our Corporate Social Responsibility effort to Alexandra Township in Gauteng, South Africa today. I took along a photocopied street map and verified street names from street signs. Some were right, some have since changed. I've added some street names, and I've offered to help out for a day to get a ride-along again this weekend with the same NGO to do some more hardcore mapping.
I took notes on waypoints as well, so I'll see if I can correlate that properly.
Not all the streets are well marked there, and some of them change their names confusingly! I'll try to get some good solid waypoint info on the name changes etc.
