Developing a method to detect flooded areas in ricefield using X-band SAR data and optical satellite image

Abstract

Approximately 561㎢ of the Pacific coast from Aomori prefecture to Chiba prefecture is flooded on Mar. 11, 2011 due to the Great East Japan earthquake. Remote sensing is effective to grasp the extensive tsunami flooded areas. In this paper, we report the result of detecting flooded areas in ricefield using X-band SAR data and optical satellite image.
