In 1861, the 12th year of King Cheoljong’s rule, Kim Jeong-ho published “Daedongnyeojido” by compiling the traditions of Korean map production. Korea was divided into 22 strata, with each stratum spanning 120 ri (approximately 47.13km) north to south, and a map was created for each stratum, which was then made into a book. The book can be folded and unfolded in sections of 80 ri (approximately 31.42km) west to east, allowing for easy use of the map. When the 22 books are all unfolded and connected, they create a large map with a length of around 6.7m and width of around 3.8m. This map is so extremely detailed that it stands comparison to maps printed today. It is a practical map that was done with extreme consideration of user convenience.

Manuscript maps by their very nature were extremely labor-intensive, with the result that few could be made. Kim Jeong-ho created the “Daedongnyeojido” map using printing blocks. He did the engraving on the woodblocks himself. He corrected some errors found in the first printed books (1861) and issued a second edition of printed books (1864). Such efforts demonstrate his tremendous passion: Kim Jeong-ho strove to create a better map, even though the improvements may have only been slight.
