Girls fleeing FGM come from very remote villages, which until recently, were not on any map. There are no road signs and it was very difficult to reach the villages, particularly at night.  Since 2015 we have been adding much-needed detail for the Mara region into OpenStreetMap, a free open-source map of the world.

Volunteers from around the world can contribute to the first stage of the process as long as they have an internet connection. The process involves identifying roads and buildings from satellite images and outlining them. There are various projects available here along with full instructions and a demo film.

We also have a Slack channel where you can ask questions about any aspect of the project and get feedback on your mapping.  The link is here 

For volunteers who are confident and accurate with their mapping, it is possible to take on the role of validating.

Once the initial work has been validated, the team on the ground in Tanzania can then add detail using their local knowledge. This final stage is done using a free smartphone app called Maps.Me.
