This map illustrates satellite-detected areas of likely standing flood waters and flood-affected land along the Cuareim River, near the main border city of Artigas, Uruguay as based on change detection methods using SPOT-5 and Formosat-2 imagery recorded 29 November and 1 December 2009. Flood water detection has been classified according to approximate confidence levels of water detection. Because flood waters under thick tree cover may not have been detected, an additional class has been added to identify those areas of thick tree cover along the main river which could also be affected by flooding. Water detection within urban areas was not possible because of limited sensor resolution. Bridges within vicinity of Artigas have been evaluated for possible flooding; bridges with indications of flooding have been highlighted in the map. This flood and bridge assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A3: 1:40,000; Projection: UTM Zone 21 South; Datum : WGS-84 (EGM-96).
