This map illustrates satellite-detected flood waters in Ha Tinh and Nghe An provinces, Viet Nam, based on a preliminary analysis of crisis Radarsat-2 data acquired on 22 October and 10 May 2010. Multiple villages appear to be flooded south west of Vinh, in addition to large sections of roads and railway. Because of the complexity of the mixed urban, marshland and aquaculture environment in this area, there is a relatively high degree of uncertainty associated with the flood water detection and classification. This flood assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A3:1:200,000; Projection : UTM Zone 48 North; Datum : WGS-84 (EGM-96).
