that's a notable difference.

If I donate $100 to a charity the net cost to me is $60 and $100 is more or
less available at the end.  If I donate $60 to the crowdsourcing then $55
arrives at the end.  So if we can get creative with a charity the money
goes further.  Different western countries have different rules but
basically if it can be channeled through a charity more cash ends up on the
ground.

West Africa, WHO are vacinating against polio is either there or not far
away, they need maps where do people live.  MSF have HOT projects around
that area.  Have a dig in HOT and you'll see sponsored projects around.
All the HOT projects suffer from having not that many people on the ground
for street names etc.  The charities have purchased image data before but
also DG and Mapbox have been very helpful to them.  If you're serious about
wanting to improve the state of the map in Bénin then working with a
charity might help both sides.

I note there is HOT mapping in Togo which is close by at the moment
"Bâtiments, routes, chemins, zones résidentielles" which I assume is the
sort of thing you're after.  Have a chat to the organizers of that project
and see which charities are involved if any.  There are four projects in
Bénin at the moment.

Currently for Cotonou there is some Mapbox imagery not the greatest but I
think you could squeeze a few more highways etc out of it.

The HOT mailing list is probably the place to start and to be honest I
thunk that is where the discussion should be taking place, but currently
they're distracted by a couple of earthquakes.  I think the most effective
mapping comes out of a mixture of local knowledge and armchair mapping
where the map is blank.  Some of the charities are very well organised MSF
for example have developed expertise in the optimum size of HOT project and
complexity.  They also have tame validators and that seems to be key to
getting a HOT project completed in a reasonable time frame.
http://wiki.openstreetmap.org/wiki/OSM_Tasking_Manager/Validating_data is
worth reading through.

The Treasury Board Canada might seem an unlikely source of assistance but
they have been instrumental in creating a open data license that is
acceptable to OSM and are working with at least one African country to use
the same license.  I think Jo has been importing a large number of schools
complete with names in one African country, it took a considerable amount
of time to get the license sorted out.  I understand if you have enough
mappers on the ground everything can get mapped but for quickness sometimes
a few high quality imports that are carefully imported can have benefits.

So if you can raise the cash fine but if you can get the imagery in other
ways perhaps a few GPS units or a few smart phones for collecting POI data
might be an acceptable way of spending the cash raised.  If your crowd
funding doesn't quite raise enough cash then sometimes there are other ways
to get the imagery.
