What these numbers are, and are not.

Records come from CKAN datasets published on data.go.th, mapped onto one schema by discovering each resource's columns rather than assuming them, and resolved into entities by unioning shared identity signals — tax ID, telephone, source-scoped registration number, and name-within-an-administrative-area. A telephone appearing in more than one province is treated as a switchboard and withdrawn as identity.

The fit score ranks only what the registry attests — contactability, OPC grading, filing recency, cross-agency corroboration and how precisely the producer is located. It does not model capacity, price or reliability, because the registry holds none of those. Hover any score to see its components.

These counts measure the registry, not the economy. A province with an active provincial office files more rows than a province with more producers and less paperwork. The same is true of every number here: they count what was filed, filed correctly, and filed recently enough to still be reachable.

Every record carries its origin. Each row names the dataset it came from, the organisation that published it, the licence it carries and the date it was retrieved — so any figure on this site can be traced back to a filing.
