The companion thailand-provinces-2017.geojson is redistributed under ODbL
1.0. Only JSON whitespace has been removed. Coordinates, attributes,
islands, and holes are retained from the upstream simplified dataset.
This download is also the machine-readable source of the rendered map.

Display transformations: local equirectangular projection at 13 N,
province extrusion, boundary outlines, region colors using YakTeaw's
existing province-to-region classification. Extrusion depth is illustrative,
not elevation. No invented jigsaw tabs or geographic displacement is added.
This is not a legal or current official boundary reference.
