Mathematical morphology approach to the detection of the off the Pacific coast of Tohoku Japan Tsunami reached farmland from PALSAR data

A great earthquake and its following great tsunami occurred on 11 th March 2011 in Japan. The agricultural fields along the coast were submerged under the sea water. For detecting such areas, the combined adaptive threshold with mathematical morphology opening method and the morphological profiles m...

Summary:A great earthquake and its following great tsunami occurred on 11 th March 2011 in Japan. The agricultural fields along the coast were submerged under the sea water. For detecting such areas, the combined adaptive threshold with mathematical morphology opening method and the morphological profiles method are tested using ALOS/PALSAR and AVNIR-2 data. The results roughly coincide with the actual Tsunami reached line.
