UNITAR/UNOSAT has produced a map of tsunami-related standing water bodies, Sendai, Miyagi prefecture. This map illustrates satellite-detected standing bodies of water remaining after the tsunami event over the city of Sendai and affected areas south in Miyagi Prefecture. Flood waters were identified through an analysis of Radarsat-2 satellite data recorded 12 March 2011 provided through the Space Charter.
UNITAR/UNOSAT works in close collaboration with and support to the Space Charter Project Manager (JAXA) for this event. The satellite image derived data (standing water bodies) can be downloaded from the link - http://www.unitar.org/unosat/node/44/1549.
