MAPPING ON MAPS.ME
We train field mappers
in rural Tanzania to add
their local knowledge to
the map using
Maps.Me, a free
smartphone app that
works offline –
particularly useful as
connectivity can be a
huge issue.

And trained people to
use the maps.
And also add missing
places to the map.

New smartphone users
see a map of their village
for the first time.
We set up networks of
digital champions to teach
others in their
communities on how to
use smartphones.
