Flood Water Level

Flood water level data, obtained by reading and recording levels from flood marks appearing on utility poles, fences, or house walls, as well as through inquiries from local residents. Data was collected using a Mobile Mapping System (MMS), referencing coordinates from the National Continuously Operating Reference Station (NCDC), in meters relative to mean sea level. This data can be used for early warning planning when used in conjunction with telemetry stations, and for verifying flood area analysis results. # Data Download * Click the __"Explore"__ button --> __"Go to Resource"__ at __"Flood Mark Data"__ to go to the Data Source page (gisservice.hii.or.th) * To download data, click the year folder, e.g., 2025, and select the desired province, e.g., Chiangrai, then find the file you wish to download.
