Has anybody tried something like this?
I've done that, just not in SA. They would usually have no problems of providing data, but you have to check the accuracy. The data I've got in Europe was sometimes up to 150m incorrect, which could sometimes take you to the other side of the road. If it is too far away other mappers can create a correct node without finding an incorrect one (thus you would end up with two petrol stations). Then you would have to think of a way capturing/entering those pois. You would have to check if petrol station is already on the map (maybe on a slightly different spot) or not. Entering/checking manually would mean A LOT of work, doing it automatically is not trivial... Just my 2c P.S. You can check/evaluate the accuracy on their websites.
