Situation overview & potential additonal flooded areas after the collapse of the Xe-Namoy dam, river overflow and heavy rain. The derived product illustrates the evolution of the event upstream and downstream Vang Ngao and Xe Kong rivers. Close-up view insets using Sentinel-1 imagery collected on the 13 and 25 July shows comparison between these dates. This is a preliminary analysis and has not yet been validated in the field.

Focus on information derived from satellite imagery and field data. Up-to-date and comprehensive satellite image derived flood analysis are displayed, together with photos automatically uploaded from the UN-ASIGN smartphone app. Additional supportive GIS data are also included on the map. https://unitar.org/unosat/node/44/2833 http://www.gdacs.org/contentdata/maps/unosat/FL/1000210/LAOS_Cover_LiveMap.jpg guid_4 Thu, 02 Aug 2018 17:21:47 This map illustrates the satellite-detected surface waters extent in Sanamxay district, Attapeu province, as observed from the TerraSar-X and Tandem-X radar imagery acquired on 27 July 2018. Satellite detected water extent analysis was performed by Centro Internazionale In Monitoraggio Ambientale Research (CIMA) & Luxembourg Institute of Science and Technology (LIST). Within the analyzed area, a total of 7,405 ha were detected as inundated, four days after the collapse of the dam.
