This map illustrates satellite detected flood water in Maungdaw & Buthidaung, Myanmar, as based on threshold classification method using Radarsat 1 & 2 data acquired on 21 November 1997 and 18 June 2010. Due to the large level of change in stream flow in this area between the pre and post image (13 years) the flood analysis extent is with a medium confidence level in terms of the water signature.
This data is a conservative estimate of the event and has not yet been validated in the field.
