With satellite images blocked by dense clouds, drones were deployed to collect high-resolution data for damage assessment and mitigation planning.<\/p>\n<p>THyCAS, a web-based GIS platform developed by <a href=\"https:\/\/www.mysa.gov.my\/\">MYSA<\/a> in collaboration with Tenaga Nasional Berhad (<a href=\"https:\/\/www.tnb.com.my\/\">TNB<\/a>), was originally designed to monitor Malaysia\u2019s hydropower dam catchment areas.
