The government of Niger, in partnership with the World Bank and a team of local volunteers, steps up the gathering of data on Niamey’s exposure to floods using drone and open source data to support disaster preparedness.
The initiative started with a team of volunteers, students and young professionals who used an open source mobile application to build a database on exposed people and assets in Niamey, the capital city.
The team has so far gathered about 15,000 data point on household and infrastructure in the region. Drone African Service, a Nigerien startup has been providing training on the use of drones to acquire high-resolution images of exposed people and facilities. This is further analyzed and modelled for flood risk of the most vulnerable communities, which will be further shared with Nigerien government authorities on the risk data portal.
Drone Africa Services trained the team on digital cartography using OpenStreetMaps and a mobile...

For instance, data sources are marked up with data about their file type, satellite/sensor and spatial coverage and whether they relate to the disaster risk management or emergency response phase. The tool features a range of filters that draw on the metadata, thereby allowing users to narrow down their search, for example, filtering available GIS software by hazard type. This ensures that users efficiently find the content that is most relevant to them. At the same time, the Portal encourages the discovery of resources related to those accessed by the user, by providing links to them on the same page. This allows for contextualisation and highlights links between resources...
