This tool aims at supporting the estimation of indicator 13.1.1 with the use of Earth Observation data. In the UN framework, indicator 13.1.1 is defined as the “number of deaths, missing people and directly affected persons attributed to disasters per 100,000 population”. The indicator is currently existing only at UN level, since there is not a perfect match in the EUROSTAT framework. The methodology has been initially developed with respect to flood events and tested in the Sahel region.
The platform allows users to choose a specific date and location in the Sahel region to estimate the number of affected buildings and people due to a flood event through an interactive map.
When executed, the application will process data from various sources, including hazard data (CHIRPS, SMAP, Copernicus DEM), and exposure data (ESA World Cover, OSM, GHSL). Results will display the estimated impact, including the number of affected buildings and the population exposed to the flood event.
