This map presents potential flood affected lands in Ubon Ratchathani Province Thailand. SPOT 4 imagery was acquired on 31 October 2010 and has a resolution of 10m. The extensive presence of rice fields along the Mun River over the observed area causes confusion with possible flood inundated land. Therefore the analysis has a high level of uncertainty and areas marked in orange can also be flood affected. The current situation has been compared with SPOT 5 imagery as of the 18 January 2008. Detected water bodies likely reflect an underestimation of all flood-affected areas within the map extent. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
