This analysis report is based on very high resolution satellite imagery acquired on the morning of 3 October 2009, the most recent imagery acquired over Sa’adah and thus does not reflect the changes on the ground reported within last three weeks. UNITAR/UNOSAT will provide updated analysis as new satellite imagery is acquired. The IDP shelter count was obtained from automated building extraction methods.

This map illustrates satellite-detected areas of likely building and vegetation damages caused by the magnitude 8.0 earthquake and resulting tsunami on 29 September 2009. A total of 11 damage sites were identified based on post-disaster satellite imagery collected on 2-3 October 2009. Each site has a corresponding high resolution focus map within the PDF document. Damage identification was significantly restricted by heavy cloud and shadow coverage, as well as by spatial resolution of the imagery. It is probable therefore that damages have been underestimated. This assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale varies for A3 prints; Projection: UTM Zone 2 South; Datum: WGS-84 (EGM-96).

This atlas map product illustrates satellite-detected areas of likely building and vegetation damages caused by the magnitude 8.0 earthquake and resulting tsunami on 29 September 2009. A total of 9 separate focus maps are included, highlighting damage sites identified from post-disaster satellite imagery collected from 30 September to 4 October 2009. Damage identification was restricted by the partial coverage and spatial resolution of the imagery, as well as by cloud cover. It is probable therefore that damages have been underestimated. This assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

This urban focus map illustrates satellite-detected areas of probable flood waters and flood-affected areas within the city of Rosso, Mauritania as based on change detection methods using Formosat-2 data acquired 16 September, and pre-crisis Spot-5 imagery acquired 10 November 2008.The primary locations of flood waters affecting the city are located in the northern and eastern edge of the urban zone. It is likely that standing water bodies located along narrow streets have been potentially underestimated. This flood assessment is a preliminary analysis & has not yet been validated in the field.

This map illustrates satellite-detected areas of possible flood waters and flood-affected areas within the central section of the capital city of Dakar, Senegal, as based on change detection methods using Radarsat-2 data acquired 4 September and pre-crisis Spot-5 imagery acquired 11 May 2009. Pre-crisis Radasat-1 from 5 September 2006 was also used. Please note there is an associated high degree of uncertainly for this flood assessment resulting from the dense urban environment and the lack of archived radar data of corresponding sensor characteristics. It is likely that standing water bodies located along narrow streets have been significantly underestimated, and that some detected water bodies shown in the map are errors resulting from the interaction of the satellite radar signals with buildings.
