The first Mapping Party of Salvador (Bahia, Brazil) happened on the last Saturday. We walked for more than two hours on the city centre and after we went to a room where we spent all the afternoon editing the data on OpenStreetMap.
On the walk there was only four people. On the afternoon, more people came along. We took pictures and marked some POIs with OSMTracker app during the walk, but our main mapping tool was FieldPapers.
