This map illustrates satellite detected potentially damaged buildings in Salt Cay island following the landfall of Tropical Cyclones IRMA-17 on 07 September 2017 and Maria on 22 September 2017. UNITAR-UNOSAT analysis used a Pleiades satellite image acquired on 23 September 2017 as post imagery. We identified 152 potentially damaged structures within the analyzed area. According to the pre-building footprints provided by Humanitarian Open Street Map, this represents ~50% of the total number of structures in Salt Cay island. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.
