Disaster Management

The RADARSAT Constellation Mission will play a very important role in Canada's natural disaster management system.

The objective is to mitigate the impacts of these disasters on the Canadian population. Interferometric synthetic aperture radar (InSAR) is a proven technique for mapping and monitoring minute changes in the ground, such as vertical displacement of the surface or structural damage caused by subsidence.

Through this mission, Canada will bolster its capacity to quickly issue alerts and respond more effectively to disasters, using the resources required to protect the population and reduce property losses.
