map Data and Mapping Process

This is the first-ever comprehensive map of private and public ferries in Lagos. It was produced through a combination of data extraction from online sources and field data collection. The scope is limited to the Lagos metropolitan area, rather than the entire state, because we are focused on reducing road congestion in the city of Lagos.

We began by identifying all locations that could potentially have ferry activities. We did this by building off a list terminals, jetties, and landings from LASWA (note: many of these locations are inactive or used for industrial/commercial purposes and therefore not open to the public). We then expanded the list by mining Google Maps and OpenStreetMap for all locations that had ferry-related keywords in their names. We hired a team of field data collection contractors to visit all the locations and determine if there is passenger ferry activity there. The field team interviewed operators at each location to document the routes that operate there and capture detailed information about the stops, schedules, and fares. They also rode the ferries and collected GPS logs, capturing the coordinates of the ferries' exact paths and stops. We then cleaned and compiled all this information into an interactive map which is freely available to the public.

Private, informal transit operations are always subject to change. This information was collected in February 2025. To stay up-to-date, we have included a user feedback feature where users can submit updates to the data.
