Here is an image acquired on May 1st, 2011 by Canadian satellite RADARSAT-2 showing the flooded areas around the Richelieu River. An image acquired a while ago allows us to visualize and appreciate the magnitude of the damage of the water overflow. The Canada Centre for Remote Sensing will produce flooding charts from these images and others to be acquired over the next few days.

Flooding in New Brunswick

Location

Description

Click map to enlarge

Recent rains and melting snow caused the Saint John River in New Brunswick to overflow its banks. Roads were closed and a number of buildings flooded. On April 30, in response to this emergency, Public Safety Canada activated the International Charter "Space and Major Disasters" to ensure continued satellite surveillance of the flooding.

The advanced capabilities of RADARSAT-2 were used for the first time in an emergency context, and provided superior information. Using RADARSAT-1 and RADARSAT-2 together, the authorities can continuously receive critical images daily. This combining of two Canadian satellites demonstrates the advantages and potential offered by a constellation of multiple sensors for monitoring a specific site in an emergency situation.
