ccaatt geocode list updated

About two years since the last update, the geocode lists at stat.dopa.go.th have been changed again. Both the central administrative list as well as the registration codes have been modified.

The changes to the ccaatt list are the biggest, however this is only because the new list only contains the subdistricts now - provinces, districts and all of the subdivisions of Bangkok have been removed. Apart from these, there is only one real change - the subdistrict Wat Sai in Nakhon Sawan is now spelled วัดไทรย์ instead of วัดไทร. It seems like that old spelling was in fact a mistake in the ccaatt table never spotted till now, as already in 1998 there was a Royal Gazette announcement which uses the name with the silent letter at end, and even the 1970 census codebook has it that way. In the 1937 census however, it was spelled with it. I haven't found any Royal Gazette announcement officially changing the spelling, so it's just a guess that the spelling has changed long time ago.

The registration codes have a few new municipalities with a code.

• 1379 for Lat Sawai town (เทศบาลเมืองลาดสวาย), Pathum Thani province
• 2059 for Prok Fa town (เทศบาลเมืองปรกฟ้า), Chonburi province
• 3464 for Kham Nam Saep subdistrict municipality (เทศบาลตำบลคำน้ำแซบ), Ubon Ratchathani province
• 3463 for Kut Chomphu subdistrict municipality (เทศบาลตำบลกุดชมภู), Ubon Ratchathani province
• 7265 for Pak Nam subdistrict municipality (เทศบาลตำบลปากน้ำ), Suphanburi province
