All the data sources E26BLC relies on

This page lists every data source E26BLC uses on the live situation map and other information pages of the site — water, rain, warnings, weather, satellites and emergency numbers — with links to the agencies that own the data.

In short
  • Most live data comes from Thai government agencies, supplemented by global open data.
  • The data belongs to the agencies that publish it. We bring it together so it is easy to see in one place.
  • This is not an official warning service. Follow evacuation orders from local authorities.

Emergency: 1784 Department of Disaster Prevention and Mitigation · 1669 medical emergency · 191 police

Member reports

Incident reports that members send through the report page are always checked by E26BLC before they appear on the map. Check-ins from devices that have not been approved before also wait for approval.

The map shows only the call sign and a pin. Check-in pins are rounded to about 100 metres, and no phone numbers or personal details are shown. See the privacy policy for details.

How we use data sources

  • We fetch data directly from the agency that owns it, never change the numbers, and show the time of the data.
  • Each topic uses one main source; important layers have a backup source for when the main one fails.
  • We credit data owners as their terms require, for example Open-Meteo and MET Norway under CC BY 4.0 and OpenStreetMap contributors under the ODbL.
  • Sources we have no permission to publish do not appear on public pages.
  • Every article lists its references at the end; see all articles under News.

Frequently asked questions

Is the live map an official warning?

No. The live map brings data from many agencies together for a quick overview, but warnings and evacuation orders must come from local government agencies such as DDPM and the province. In an emergency call 1784 or 1669.

What does the map show if a main data source fails?

Important layers have backups: the Thai Meteorological Department radar is backed up by RainViewer, Air4Thai PM2.5 by model estimates, weather forecasts by MET Norway, and airport weather by the Royal Thai Air Force Weather Wing.

If a source cannot be reached for a while, the system shows the latest data it fetched, so always check the time of the data before you use it.

How often is the data updated?

Each agency updates on its own schedule, so the live map shows the update time of every source in the dashboard header and the time of the data on each card.

Can I reuse data from this site?

Agency data can be used under each owner’s own terms — check the agency’s website. For E26BLC’s own text, images and design, see copyright and terms of use.

How do I report wrong data or suggest a new source?
