THE DEVASTATING CYCLONE IDAI AND FLOOD MAPPING FROM SPACE:
21 march 2019
On March 14, the cyclone Idai made landfall on the coast of Mozambique, causing severe rainfall and widespread flooding throughout Mozambique, Malawi and Zimbabwe.
Synthetic Aperture Radar (SAR) images captured by the Sentinel-1 satellite can be used to accurately map the extent of flooding over large geographical areas, using advanced image analysis and processing.
Mozambique’s fourth largest city, Beira in the Sofala province, was one of the most severely affected areas.
By using SAR imagery, we have mapped the flooding’s caused by the cyclone around the city.
These maps are essential for informing authorities and development organizations about the geographical extent and impact from flooding events, in order to target emergency response and development efforts.
Contact us if you want access to the imagery in full resolution or if you are interested in hearing more about flood mapping from space.
As part of the ongoing support to the Zambezi Watercourse Commission (ZAMCOM) our project EO4SD Water has mapped the extent of recent floodings in Mozambique and Malawi, see link below.
