Primary source:中国历代战争年表 (上卷 + 下卷)
Chronological Tables of Wars in Chinese History, vols. I–II解放军出版社 (PLA Press), 2003 / 2010
Covers approximately 3,800 engagements from the legendary era through 1911. The editorial rules exclude engagements without actual combat, making this source more selective than the other large compendiums of Chinese military history, 中国战典 (approx. 12,800 entries) or Gu Zuyu's 读史方舆纪要 (approx. 6,200 entries).
Geocoding:The source names locations at prefecture or county level rather than exact battlefield. The geocoding here relies on CHGIS V6 (Harvard/Fudan, 2016), a reference database of approximately 15,700 historical place names with dynastic date ranges, essentially a historical atlas of Chinese administrative geography from antiquity through 1911. The database is filtered to each battle's own dynasty, so a Tang battle is matched against Tang administrative geography rather than later boundaries. Coordinates represent the administrative center of the matched location, setting a precision ceiling of roughly ±10–50 km. Frontier, steppe, and overseas campaigns carry wider uncertainty. Of the source's approximately 3,800 entries, 3,735 were successfully geocoded; the remainder lacked identifiable locations. Dates and coordinates have been cross-checked against the source text across multiple review passes.
| Tier | n | ~correct | Precision |

Standard CHGIS-matched to place named in source; not individually reviewed | 3,171 | ~84% | ±10–50 km |
Low Sparse description; location approximate | 74 | ~68% | ±50–150 km |
| Overall | 3,735 | ~87% | ±10–50 km |
