Niger floods

Pléiades and TerraSAR-X support emergency mapping

August 2012, the Pléiades and TerraSAR-X satellites were tasked to acquire imagery of the devastating floods in Niger.

West Africa has been in the grip of torrential rains since July. In mid-August, heavy rains in Niger bring major floods. On 29 August, the Pléiades satellite operated by Airbus Defence and Space is tasked to acquire priority imagery of 2 towns identified by French civil protection teams and local authorities under the «International Charter on Space and Major Disasters»: Dosso, where some 10,000 homes have been destroyed, and Agadez, where the river has swollen and flooded the town.

Rapid mapping

On the morning of 30 August, the first Pléiades very-high-resolution images of Dosso and Agadez are acquired and delivered to International Charter operators at 16.00. The images are processed in less than 7 hours by the SERTIT to generate maps highlighting flood zones and the extent of flooding around urban areas.

The SPOT 5 and TerraSAR-X satellites also operated by Airbus Defence and Space swing into action in the days after the floods.

Maps arrive in Niger

The flood maps are dispatched immediately to the Niger authorities and French civil protection teams to support food and health relief operations coordinated by the Niger authorities, humanitarian organisations and other partners.
