This map illustrates satellite-detected areas of wet & saturated soils in Garut Regency, Jawa Barat Province, Indonesia, extracted from TerraSAR-X images (3 m) acquired on 22 April 2012 (pre-event) and on 25 September 2016 (post-event). Waters along the Kali Cimanuk remain in the riverbed without causing floods. Possible wet/ saturated soils are visible as of 25 September 2016 over mainly agricultural areas. As of 25 September 2016, ~ 450 ha of lands were potentially affected, mainly in Karangpawitan & Banyuresmi districts. The exact limit of flood waters is uncertain because of the low spatial resolution of the satellite data used for this analysis. Detected water bodies likely reflect an underestimation of all flood-affected areas within the map extent. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.
