Within the analysed extent of about 8,300 km2, a total about 332 km2 of land appear to be flooded as of 11 September 2019. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.Important Note: Flood analysis from Sentinel-1 imagery acquired on 11 September 2019 may seriously underestimate presence of standing flood water in built up areas due to backscattering of the radar signal 1100181 FL20190905LAO UNOSAT@UNITAR.ORG (UNOSAT) FL https://unosat-maps.web.cern.ch/unosat-maps/LA/FL20190905LAO/UNOSAT_A3_Natural_Portrait_FL20190905LAO_Savannakhet_LAOS_11092019.jpg http://unitar.org/unosat/node/44/2944 15.97 104.695 17.466 104.695 17.466 105.477 15.97 105.477 15.97 104.695 17.466 104.695
