This map presents potential standing flood waters/ flood affected land over the affected area surrounding Tonle Sap Lake, Cambodia following recent heavy rainy season. This analysis indicates that flood waters have expanded in the lake area between 28 August and 27th October 2011. Please note that the exact limit of the flood waters is uncertain because of the relatively low spatial resolution of the satellite sensors used for this analysis, 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.
