This map presents the potential flood affected lands in and around Ayuthaya Province and Chao Phraya river in Thailand. The analysis reaches from the province of Lopburi in north till Pathum Thani in the south.There is possiblitity of floods extending till Bangkok in the near future. MODIS imagery was acquired on 29 October 2010 and has a resolution of 250m. Due to the delta character, cloud coverage, extensive presence of rice fields over the observed area and lack of corresponding pre-crisis MODIS data, the analysis has a high level of uncertainty. 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.
