Hi there, I'm very proud to announce that I started to map my first favela here in Rio, the Favela Santa Marta [1] [2] [3]. It has a funicular system to the top, and I've added a couple of POIs.
However (and obviously), the GPS tracks were completely erratic due to the sub-meter wide footpaths. I've tried with my Nokia N95 GPS. It is very dense [4] there, you can check how erratic was the log [5]. But it is already something! :D Judging the satelite image, what do you think it would be better: purchasing sub-meter pixel satellite imagery, an expensive GPS unit or a combination of both? I believe that once the main footpaths/stairways are mapped, we can have mapping parties with Walking Papers. I'd love to have the kids helping by adding POIs, for instance. Perhaps talking with the local school...
