This map presents the standing flood waters over the affected Central Provinces of Thailand based on analysis of satellite data recorded 01 November 2011. Based on a recent time series comparison, there are strong indications that flood waters have strongly risen within the northern, western and eastern sections of Bangkok, and further, have not significantly changed in spatial extent north of the city over the last two weeks. The highest concentration of flooding is located within the provinces of Phara Nakhan Si Ayudhya, Nakhon Sawan, Chaitan, Pathum Thani, Nakon Pathon, Ang Thong, Lopburi, Singburi and Suphanburi. It is likely that significant areas of flood waters have not been identified over Bangkok because of partial cloud cover in the area. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR /UNOSAT.
