The datasets

Everything this project asserts, it asserts from a file you can download. This shelf is all of them — what each one is, where its facts come from, what re-use must honour, and the checksum that says the file you fetched is the file the site argues from.

Checksums are SHA-256 of the served file, computed at build time — the catalogue fails the build if a served dataset is missing from this page or a listed file is missing from disk. OSM-derived geometry is ODbL and stays ODbL; the licence line on each entry is the one that binds.

The Bangkok heritage register

1.3 MB571 records25fff1e3138a

All 571 Fine Arts Department registered ancient monuments in Bangkok, each relocated to building precision where the published coordinate is too coarse — with the resolution method recorded per site (register coordinate, OSM name match, or honestly left unpinned).

The rowhouse atlas

100 KB64 linestring + point0ef6244d23a7

Rattanakosin moat & river edge

The moat (คลองรอบกรุง) and the Chao Phraya river edge of the royal island, as line geometry — 10 moat fragments and 16 river fragments. Carries world block coordinates alongside the original WGS84, so every placement in the Minecraft build is auditable back to the map.
