This image was compared with a pre-crisis SPOT 5 with 10m resolution showing the situation as of 6 December 2007. Due to the extensive presence of rice fields over the observed area and a pre image of the same season, 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 of confusion with cultivated rice fields. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
