SATELLITE ASSESSMENT CLASSIFICATION:
This map presents the potential flood affected lands in and aroundAyuthaya Province and Chao Phraya river in Thailand.The analysis reaches from the province of Lopburi in north tillPathum Thani in the south.There is possiblitity of floods extending tillBangkok in the near future. MODIS imagery was acquired on 29October 2010 and has a resolution of 250m. Due to the deltacharacter, cloud coverage, extensive presence of rice fields over theobserved area and lack of corresponding pre-crisis modis data, theanalysis has a high level of uncertainty. Detected water bodies likelyreflect an underestimation of all flood-affected areas within the mapextent. This analysis has not yet been validated in the field. Pleasesend ground feedback to UNITAR / UNOSAT.
