Each year, disasters around the world kill nearly 100,000 and affect or displace 200 million people. Mapping can help change this.

Organizations use Tasking Manager to create mapping projects for areas around the world where data is needed to help save or improve lives.

Mapping

Volunteers use satellite imagery from OpenStreetMap to trace buildings, roadways, and other features.

Validation

Experienced volunteers check the map data to ensure it is high quality.

Using the data

Humanitarian organizations use the map data to plan for disaster response and other life saving activities.

Who uses the maps?

Trusted global organizations use Tasking Manager to get the map data they need to reach those in need.

In the early days of the Cyclone Idai response, IFRC was looking for detailed maps to get a sense of the scale of the flooding, which were also used for search and rescue operations. Later on, we had requests to identify where certain buildings, such as health centres or hospitals, were located so our health team could assess the damage and medical needs of patients.
