Daedongyeojido
Daedongyeojido (also Daedong yeojido, , lit. "The Great Map of the East Land") is a large scale map of Korea produced by Joseon dynasty cartographer and geologist Kim Jeong-ho in 1861. A second edition was printed in 1864. One source describes it as the "oldest map in Korea". Daedongyeojido is considered very advanced for its time, and marks the zenith of pre-modern Korean cartography.
