This map presents the potential flood affected lands around Pak Nam Pho,Nakhan Sawan Province and Chao Phraya river in Thailand. There is possiblitity of floods extending inside Pak Nam Pho town in the near future. PALSAR imagery was acquired on 30 October 2010 and has a resolution of 100m. Due to the extensive presence of rice fields over the observed area , the analysis has a high level of uncertainty. Detected water bodies likely reflect an overrestimation of all flood-affected areas within the map extent, because ov the used L-band SAR sensor. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
