TGAZ-SQLite
The Temporal Gazetteer (TGAZ) of the China Historical GIS (CHGIS) as one SQLite file. It has 82,117 historical placenames from 763 BCE to 1911 CE, with 245,042 spellings (simplified and traditional Chinese, pinyin, Tibetan), jurisdiction links over time, and historical notes.
Files
| File | What it is |
|---|---|
tgaz_20260325.zip |
the database (tgaz.db, 228 MB unzipped, 62 MB zipped) |
latest.json |
the current release: file name, SHA-256 checksums, download URL |
Download
The easiest way is the setup command of the
tgaz-sqlite skill:
python3 scripts/query_tgaz.py setup # downloads, checks the checksum, unzips
It puts the file at ~/.local/share/sino-authorities/tgaz.db. By hand:
curl -L -o tgaz.zip https://huggingface.co/datasets/kltng/tgaz-sqlite/resolve/main/tgaz_20260325.zip
unzip tgaz.zip # gives tgaz.db

Known data problems
- About 6,000 rows (mostly POLYGON records,
hvd_90xxxIDs) have longitude0.00000. On a map they land in Africa. The skill's--good-coordsflag drops them. - 251 rows end before they begin (e.g.
hvd_112536). mv_pn_srch.parent_vnis the earliest parent, not the parent in a given year. Usepart_offor a given year.
