A major cyclone, named Cyclone Aila, passed through the southwest region of Bangladesh and West Bengal in India, bringing damage to both countries. According to current local reports, approximately 100,000 people in Bangladesh evacuated, the number of fatalities stood at 120, and several thousand homes were reported to have been damaged by the high waves. In addition, close to 500 people were reported to be missing, and the number of victims may continue to increase. In India, 30 people died, and approximately 100,000 people were reported to have lost their homes (From the homepage of the Japanese Red Cross Society).
Imaging using TerraSAR-X (Synthetic Aperture Radar)
PASCO carried out emergency imaging of the affected areas using the synthetic aperture radar (SAR) satellite "TerraSAR-X," at 12:00 a.m. (UTC) on June 2.
Although the meteorological satellite reported some cloud cover over a part of the imaging area during the acquisition, it was completed successfully.
Based on the acquired data and taking advantage of the weakness of the backscattering strength of microwaves on the water surface, we attempted to extract only single images of the inundated region.
|Acquisition dates and times||:||June 02, 2009, 12:00 (UTC)|
|Angle of incidence||:||25.0°|
|Polarized wave||:||Single polarization (HH)|
History of Information Released
|First release date||:||June 8, 2009 (Monday)|
From the perspective of understanding the damage situation caused by the disaster, and of providing information to the relevant organizations, PASCO carried out estimations for the areas of damage immediately utilizing SAR satellite images, which are not impacted by weather conditions.
We express our deepest sympathy to all who have been affected by the disaster.
We will strive even harder to be of service to all through the application of our spatial information processing and analysis technologies, as well as through our disaster prevention consulting expertise, in order to obtain accurate information on the disaster situation and assist in the recovery of the affected areas.
