Ok, finally, I managed to upload and edit a few tracks in an around Mombasa, Kenya, as part of me testing the feasability of employing GPS units to field teams in national household surveys and uploading their tracks to OSM.
So far so good I guess, not too much work, not too complicated - this session just with me uploading my own field visits. Next step is to hand a unit to 3 drivers shuttling teams around the slums and getting the units back for upload in a month or so.
