Kim Sa-hyeong, Yi Mu and Yi Hoe combined Yuan maps with maps of Joseon and Japan to make the world map Honil gangni yeokdae gukdo jido.
By order of King Seongjong, No Sa-sin, Seo Geo-jeong, Yang Seong-ji and others compiled the Dongguk yeoji seungnam, a geography recording the history, landscape, customs and notable people of every county.
A map of Korea by Jeong Sang-gi, the first to use a scale — the "hundred-ri ruler".
Kim Jeong-ho made the Cheonggudo, a two-volume atlas dividing the country into a grid, whose pages join up into a map of the whole country — the groundwork for the Daedong yeojido.
Kim Jeong-ho published a woodblock map of the whole country in 22 folding sections; laid out together they form a map nearly seven metres tall.
Twelve of the woodblocks Kim Jeong-ho carved to print the Daedong yeojido survive, in the National Museum of Korea and Soongsil University; they were designated a Treasure in 2008.
