Survey Map in Qing Dynasty
The Qing Dynasty (Chinese: 清朝; pinyin: Qīng cháo; Wade–Giles: Ch'ing ch'ao; Manchu: Daicing gurun; Mongolian: Манж Чин Улс), also known as the Manchu Dynasty, was the last ruling dynasty of China, ruling from 1644 to 1912 (ostensibly with a brief restoration during the short-lived Empire of China).
When the time of Emperor Kangxi’s reign in Qing Dynasty and because of import of western cartography skills, he realized Chinese map were not accurate enough and needed scientific methods to mapping. Thus he sponsored a national wide geodesy and mapping based on astronomical observation and triangulation measurement. It took ten years to complete the map named Huang Yu Quan Lan Tu from 1708 AD, which was the first on-the-spot survey map. It had 41 framings based on province boundary and have following characteristics:
- Using pseudo-cylindrical projection and latitude and longitude cartography methods
- Using writing Chinese and Manchu language to name place together that Manchu to name boundary and writing Chinese to name inland content
- Survey map of Taiwan province in the first time
Besides cartography, the unification of scale measurement and the field measurement of meridian of earth are both contributed to the development of cartography in Qing Dynasty and help to improve quality of maps in a great deal.

Famous quotes containing the words survey, map and/or qing:
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
