OpenStreetMap Contributors Needed to Map Khartoum Ahead of New Radar Satellite Imagery
Over the past two years, conflict in Sudan has driven the country into one of the world’s largest humanitarian crises. Satellite radar coverage gaps have hindered efforts to assess damage to urban areas. With the launch of the Sentinel-1C radar satellite by the European Space Agency, that gap is beginning to close — but a comprehensive dataset of building footprints from OpenStreetMap (OSM) is essential to make this satellite data actionable.
Mapping Freetown from above: How a city and its residents are producing their own aerial imagery datasets
Freetown’s first citywide drone mapping project redefined urban planning by putting communities at the center — piloting drones, producing data, and shaping the future of their city.
