This map illustrates the satellite-detected surface waters extent and evolution in Phu Yen Province, Vietnam, as observed from the Sentinel-1 images acquired on 07 November 2016 and 01 December 2016. Within the analysed zone, representing ~85% of the total province area, an increase of surface waters extent was observed between the 07 November 2016 and 01 December 2016. ~19,200 ha of surface water were observed the 07 November 2016 and reached ~26,400 ha the 01 December 2016. All over the analysed area, it corresponds to an evolution of about 37 % : Tuy Hoa District (+3,320 ha), Dông Hòa District (+2,000 ha), Phu Hòa District (+1,460 ha) and Tuy An District (+1,340 ha). This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
