This map presents the standing flood waters over theaffected
Central Provinces of Thailand based on analysisof satellite data
recorded 24 October 2011. Based on arecent time series comparison,
there are strongindications that flood waters have strongly risen
within thenorthern, western and eastern sections of Bangkok,
andfurther, have not significantly changed in spatial extentnorth
of the city over the last two weeks. The highestconcentration of
flooding is located within the provinces ofPhara Nakhan Si Ayudhya,
Nakhon Sawan, Chaitan,Pathum Thani, Nakon Pathon, Ang Thong,
Lopburi,Singburi and Suphanburi. It is likely that flood watershave
been systematically underestimated along highlyvegetated areas
along main river banks, and within built-up areas within Bangkok
because of the specialcharacteristics of the satellite data used.
This analysishas not yet been validated in the field. Please
sendground feedback to UNITAR /UNOSAT.
