Imaging on July 30, 2011, Using Synthetic Aperture Radar (SAR) Satellite "TerraSAR-X"

Imaging Specifications

Acquisition dates and times : July 30, 2011, 17:28 (JST)
Angle of incidence : 19°
Imaging mode : StripMap
Product type : EEC
Polarized wave : HH
Image

We observed inundation in the areas around the Honai and Tsukanome districts, where flooding reached above floor levels as a result of flows from Shimojogawa River and other factors. (Red circles in the figure)

Image

Using the images acquired by synthetic aperture radar (SAR) satellite "TerraSAR-X" on July 30, 2011, the water regions (rivers, lakes and marshland, range of inundation, etc.) were extracted. Water levels at Shinanogawa River were estimated to have risen to the flood channel.
