ข้อมูลระดับน้ำท่วม

This dataset is published in Thai only. Titles are shown as published — we do not machine-translate source data.

Flood level data, obtained by reading and recording height levels from flood marks visible on utility poles, fences, or house walls, as well as through inquiries from local residents. Data is collected using a Mobile Mapping System (MMS), referencing coordinates from the National Continuously Operating Reference Center (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 "Survey" button --> "Go to Repository" at "Flood Level Data (Flood Mark)" 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.
