The map below is of the Korean island of Ulleungdo (鬱陵島). It comes from the atlas "Paldo Yeojido" (八道輿地圖), which is believed to have been made sometime in the mid 1700s. The atlas said that Ulleungdo had a circumference of bout 200 ri (80 kilometers), and measured about eighty ri (32 km)from east to west, and about fifty ri from north to south (20 km). The atlas also lists some of the flora and fauna found on the island at the time, which included "sea lions" (可支魚). The map below can be found in the Gangwon Province (江原道) section of the atlas (江原道 輿地圖), the cover of which is pictured on the left. The map and atlas are stored in the National Library of Korea.
The mapmaker drew Ulleungdo in a circular shape, which was a common way to draw the island at that time. A small island was also drawn off the east shore of Ulleungdo and labeled as "所謂 干山島." That translates as "the so-called Gansando," which was almost certainly a misspelling of Usando (于山島). Korea claims that Usando was the old Korean name for "Dokdo" (Liancourt Rocks), but this map of Ulleungdo and many others show that Usando was just a neighboring island of Ulleungdo. In fact, there are no Korean or Japanese maps that show Usando as Liancourt Rocks (Dokdo).
The map also shows five small islands off the southern shore of Ulleungdo, which may have been a mapping errors since many, but not all, of Ulleungdo's neighboring rock islets (石島) are off its nortern shore. At any rate, the map shows Ulleungdo with six, small neighboring islands, of which Usando is the most prominent.
