The State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing at Wuhan University provided key remote sensing monitoring and analysis results in a recent evaluation report published on the official website of Sri Lanka's Disaster Management Center.

The university’s radar team, led by associate professors Shi Lei and Zhao Lingli, utilized their independently developed radar remote sensing flood monitoring technology to accurately map flood inundation areas. These results have been adopted by the Sri Lankan authorities for direct use in emergency rescue decision-making.

The emergency response was organized under the coordination of the United Nations Office for Outer Space Affairs (UNOOSA) and the United Nations Development Programme (UNDP) through the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER)Regional Support Office in China, hosted by Wuhan University.

The team, under the unified coordination of Professor Li Xi, began operations on Nov 28. They utilized synthetic aperture radar imagery from domestic commercial satellites "Chaohu-1" and "Shenqi-2", combined with their long-term expertise in flood disaster remote sensing monitoring, to extract inundation information within three hours of receiving data.

They have continued to conduct multi-phase dynamic monitoring, providing timely and reliable spatial information support for assessing the flood situation in Sri Lanka.

The center is conducting rescue operations based on the remote sensing analysis results provided by the WHU team, which will continue to track the evolution of the disaster, update monitoring data, and provide ongoing technical support for local post-disaster recovery and the construction of medium- and long-term disaster prevention and mitigation systems.
