**UNOSAT code: FL20240912THA** This map illustrates cumulative detected water using multiple satellites in Chiang Rai Province, Thailand from 1 August to 22 October 2024. Within the boundary of Chiang Rai Province of about 11,600 km², a total of about 875 km² of land appears to be affected by flood waters, with around 700 km² of cropland inundated. Based on Worldpop spatial demographic data, about 94,100 people are exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT). This work is the result of collaboration between UNOSAT and GISTDA operating under the agreement of the UNOSAT Rapid Mapping Partners Initiative Programme
