thanks to all those who contributed to this response: the progresses of
the map are important and your work had a strong impact down there
amongst the TechCamp participants as well as among GISers I met from the
UN, Gov Agency, Academics and Techs. Furthermore it fostered the
remobilization of the nascent Senegalese OSM community by heating things
up. </div>

footway) which seems well suited for the most narrow streets. I would
refrain when mapping remotely to use living_street which calls for
on-the-ground knowledge and de facto right of way between vehicle and
pedestrians. This is a tag to better explain/ portray and push to the
mappers down there. More generally, with Jaakko, Brian and Sev we feel a
need to better articulate guide on using highway values below tertiary
in developing countries.</div>

those uses are really changing over time in the course of the day.
Those usages also apply to a good deal of streets where as a kid, I
learned playing street soccer and hanged out for long hours in wedding/
funerals and later party.
