The World Flood Mapping Tool

A useful toolkit. The tool allows scientists, organizations and curious members of the public to adjust variables to see where floods have occurred in the past. Users can select a location and time-frame, and the tool, which draws on decades of data from remote-sensing satellites, produces a flood map at a 30-meter---about 100-foot---resolution. There is no single factor exacerbating flooding across the globe, but rather a combination of local factors. In some cases, the impacts of flooding are made worse by the geology of the area or the way land is being used.
