Hi there,<br><br>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.<br><br>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<br>
<br>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?<br><br>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...<br>

4: Check on Google Maps sat imagery (just to have an idea because Yahoo! imagery is very poor): <a href="http://maps.google.com.br/maps?f=q&source=s_q&hl=pt-BR&geocode=&q=dona+marta,+botafogo,+rj&sll=0,0&sspn=74.600551,158.027344&ie=UTF8&hq=&hnear=Botafogo+-+Rio+de+Janeiro+-+RJ&ll=-22.947333,-43.194632&spn=0.002262,0.004823&t=k&z=18" target="_blank">http://maps.google.com.br/maps?f=q&source=s_q&hl=pt-BR&geocode=&q=dona+marta,+botafogo,+rj&sll=0,0&sspn=74.600551,158.027344&ie=UTF8&hq=&hnear=Botafogo+-+Rio+de+Janeiro+-+RJ&ll=-22.947333,-43.194632&spn=0.002262,0.004823&t=k&z=18</a><br>
