SATELLITE ASSESSMENT CLASSIFICATION:
This map presents the potential flood affected lands around the townof Phra Nakhon Si Ayutthaya in Ayutthaya Province and close to theChao Phraya River. SPOT 4 crisis imagery was acquired on 30October 2010 and has a pan-sharpened resolution of 10m. This imagewas compared with a pre-crisis SPOT 5 with 10m resolution showingthe situation as of 6 December 2007. Due to the extensive presenceof rice fields over the observed area and a pre image of the sameseason, the analysis has a high level of uncertainty. Detected waterbodies likely reflect an overrestimation of all flood-affected areaswithin the map extent, because of confusion with cultivated rice fields.This analysis has not yet been validated in the field. Please sendground feedback to UNITAR / UNOSAT.
