Daedongyeojido ("The Great Map of the East Land") is a large scale map of Korea produced by Chosun Dysnasty cartographer and geologist Kim Jeong-ho in 1861. Although no modern survey techniques were used, it is remarkably similar to modern maps. This marks the zenith of pre-modern Korean cartography.
