Community Mapping for Flood Resilience

Dar Ramani Huria

Ramani Huria is community-based mapping project in Dar es Salaam, Tanzania, training university students and local community members to create highly accurate maps of the most flood-prone areas of the city using OpenStreetMap.


OpenStreetMap is a web project to create a free and open map of the entire world, built entirely by volunteers surveying with GPS, digitizing aerial imagery, and collecting and liberating existing public sources of geographic data.


InaSAFE is a free software that produces realistic natural hazard impact scenarios for better planning, preparedness and response. It combines data from scientists, local governments and communities to predict the likely impacts of future disasters.

Get Data

Ramani Huria uses the OpenStreetMap platform, and all data is free and accessible for anyone to use. All content generated through the project is shared on OpenStreetMap and through our website.
