Preliminary Flood Mapping after the Southwest Monsoon in Myanmar
Early August 2019, the Southwest monsoon hit Myanmar flooding several areas. The Geoinformatics Unit, RIKEN Center for Advanced Intelligence Project conducted a preliminary mapping of the affected areas using earth observation data. The Sentinal Asia Program provided the high-resolution ALOS-2 PALSAR-2 data used in this analysis.
To detect the flooded areas, we carried out a change detection analysis using a pre-event SAR data acquired on September 13, 2018, and a post-event SAR data from August 15, 2019. The image below shows the comparison of the pre- and post-event images, and the detected flooded areas (blue segments) in Bago, Kayin, and Mon.
