China GEO Supports Thailand, Sri Lanka and Indonesia Flood Disaster Response
15 Jan 2026
From November to December 2025, continuous heavy rainfall and rare tropical cyclones unleashed widespread flash flooding and landslides across South and South East Asia, killing more than 600 people with hundreds still missing.
Responding to requests from the United Nations Institute for Training and Research (UNITAR), the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP), China GEO Secretariat activated its Disaster Data Response (CDDR) Mechanism to provide high-resolution satellite imagery in support of disaster response.
ChinaGEOSS Data Sharing Network (ChinaGEOSS DSNet) hosted by the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) was responsible for the whole process of disaster data response. Chaohu-1, Shenqi-02 and AIRSAT-01 satellites were assigned 12 emergency observation missions over the flood inundated area in Thailand, Sri Lanka and Indonesia.
As of December 19, 127 scenes of satellite post-disaster SAR imagery were collected, and the data volume reached 103.53GB. These data have been provided to Thailand’s Geo-Informatics and Space Technology Development Agency (GISTDA), Sri Lanka's Disaster Management Center (DMC) and Indonesia’s National Research and Innovation Agency (BRIN) to help them carry out on-site verification, analysis, and evaluation of the disaster situation.
Established in 2016, the CDDR is responsible for coordinating the provision of Chinese high-resolution satellite data and disaster analysis products to disaster-affected countries. The objective is to strengthen space-based emergency response capability with international partners (UNESCAP, UNITAR, GEO,and CODATA) to bridge the digital divide. In the past years, the CDDR have provided humanitarian assistance for over 100 major disasters in 54 countries.
