The International Symposium on Sino-French Geodetic Survey of the Qing Dynasty in the 18th Century is scheduled to be held in Sanya on November 14th-18th.

The conference will focus on three themes: Investigation of the "Hai Pan Nan Tian" stone inscription, Geodetic survey in the Kangxi-Yongzheng-Qianlong period, and Comparative study of geodetic surveys in China and France in the 17th and 18th centuries.

The geodetic survey of the Qing Dynasty which started in the Kangxi reign period (1662-1722) was an unprecedented geographical achievement not only in Chinese history, but also in world history.

During the survey carried out from 1707 to 1717, 641 locations were used as control points for triangulation. A stone with inscriptions “Hai Pan Nan Tian” (where the sea marks the southern territories) in Tianyahaijiao, made by officials sent by Emperor Kangxi in 1714, is the only existent control location to date.

On November 15th, the 300th Anniversary of the Stone Inscription “Hai Pan Nan Tian” will be held at the Tianya Haijiao Scenic Spot.
