African NGO maps out the waterways of Lagos’s forgotten slum

Officially, the floating Lagos slum of Makoko does not exist. It does not appear on any city planning documents or maps. But that is about to change, thanks to a team of local volunteers and South Africa-based NGO Code For Africa. Using geolocalising technology, they navigate the waterways of this floating slum to create a map that they hope will improve the lives of those living here.
