The Map that Saves Lives
What This Means
When disaster strikes—be it a flood, earthquake, or conflict zone—response teams need accurate, up-to-date maps to reach those in need. OpenStreetMap, with its open data and global community, fills critical mapping gaps in real time. Powered by volunteers and supported by humanitarian organizations, OSM enables aid agencies to navigate chaos with clarity.
How OSM has been contributing to saving lives
Responding to Floods in Libya (2023)
After Storm Daniel, volunteers mapped entire cities to help assess flood damage and coordinate humanitarian aid distribution.
Supporting Malaria Elimination in Mozambique
Mappers added thousands of unmapped buildings to support indoor residual spraying campaigns, protecting vulnerable populations from malaria.
How you can contribute
You don't need a cape or a degree to save lives—just a mouse and a little heart .❤️
