Hi everyone, It is inspiring to hear of these projects in Bangkok and Cartagena! <3
Depending on the wind and when the rainy season is about to start in Bangkok, putting a kite up in the air with a small camera could be the fastest and most community-engaged / hands-on / accessible / repeatable way to get aerial imagery: http://www.bangkokpost.com/learning/learning-news/524907/the-kite-flying-season-in-bangkok Once you have an aerial photo (by balloon/kite/drone/reaaaaally long bamboo pole <https://publiclab.org/wiki/balloon-mapping>:), you can place (georeference) it in http://mapknitter.org/, then it's one click to loading that base imagery in any/all of OSM's editors for tracing over. I copied the grassroots mapping list where there are people to chat with about DIY aerial imagery for mapping.
