This Synthetic Aperture Radar (SAR) image captured by MDA’s RADARSAT-2 satellite on September 8, 2017 depicts Hurricane Irma. The dark centre depicts the relatively calm ocean surface within the eye, which spans approximately 30 kilometers, while the lighter gray surrounding the hurricane depicts rough waters caused by torrential rainfall and high winds. The 500 km x 500 km image gives a sense of the immense size of the storm. To download the image shown above, please visit our Image Gallery.

These two Synthetic Aperture Radar (SAR) images captured by MDA’s RADARSAT-2 satellite depict images of the Houston, Texas area. The image on the left shows the area pre-flood captured in 2016, and the image on the right, shows the same area as of August 31, 2017.  The magnitude of the flooding in this area is depicted in the August 31, 2017 image with water generally appearing as darker areas in the image.

The report below shows MDA’s flood extent map derived from the image acquired over Houston on August 31. It clearly depicts the widespread flooding that persists in the Houston area. The areas highlighted in blue show the flood extent based on evaluating the change in RADAR signal between the ‘dry’ and ‘flood’ images. With RADARSAT-2’s unique wide-area imaging capabilities and ability to image regardless of cloud cover or light conditions, MDA’s RADARSAT-2 and GIS-ready flood maps are ideal for supporting decision making for Emergency Management authorities. MDA has been acquiring data and supplying information to support agencies for Hurricane Harvey since it’s landfall on August 26th. The information showing the location and extent of flooding have been updated regularly as the disaster evolves, giving disaster relief agencies the information needed to effectively respond and minimize threats to human safety and surrounding infrastructure.
