This map is based upon the surveys made by the Jesuit Fathers Felix da Rocha 傅作霖 and Joseph d’Espinha 高慎思 between 1756 and 1759. The cartography was completed by Fr. Michel Benoist 蔣友仁 in Beijing. Benoist and his Chinese co-workers prepared the wood-cut edition in 1769, and under their guidance it was engraved on copper plates (銅版) in 1775. Since then, these plates and the original maps have been kept in the Palace unseen by the public until 1924, when the Museum staff discovered a complete set of the original copper plates. This example is one of only one-hundred copies that were run on the original plates.
The map was commissioned by the Qianlong emperor in order to utilize Jesuit expertise in cartography in creating an accurate map of the empire, especially the restive western regions of Xinjiang and Qinghai, as well as the Yunnan-Guizhou region and the Tibetan plateau. Thus the map covers almost the entire Asian continent, and consists of 104 sheets using the traditional Chinese rectangular-grid mapping system modified to suit longitude and latitude. The small booklet map shows the folio sheets with the orignal for comparison. Reference: Needham, Science and Civilisation in China, v. 3, p. 586.
Note on OCLC record: Map consists of 103 sheets, arranged in 13 horizontal strips. Also uses oblique grids and is divided into 13 horizontal strips, each of five degrees of latitude, with 7.8 cm between latitude lines. Original version: Qing Qianlong Neifu yutu. China : engraved by Michel Benoist on copper plates in 1773 and printed in 1775. Based on earlier map "Huangyu quanlantu."
Scale: ca. 1:1,500,000
