The COSMHA team came in for a training today on aerial imagery tracing and some review of fundamentals. Despite the initial remote Haiti OSM response being 100% aerial imagery tracing, the team on the ground has focused exclusively on GPS.
He came it to review fundamentals. Over the day we covered subjects: road classification, positioning POI for accuracy vs cartography, how to use imagery in combination with GPS, the inaccuracy of GPS, login/logout of JOSM, resolving conflicts in JOSM, and the finer points of topology! I'm sharing the lessons from today with the folks back in Kibera, who will soon be doing the same kind of exercise with Sebastian.
