3) 「欝陵島図 in 『朝鮮地図』
"朝鮮地図"is a map which describes 8 prefecture of Choson era and assumed to have been made by the order of the 21th King of Choson, 英祖 in 1770. It is currently owned by Kyujangkak of Korean study center of Seoul National University. It were drawn on ruled paper with relative scale or the graticule, and each county is drawn, and it is assumed that the distance of the location information and accuracy in the direction are expected when it was made. It is said that relative scale is lined in every 20里, and there was 備辺司 sign. Therefore, it can be said that this map is a government manufactured official map, either. The feature of this map is it is a little longer from east to west than the shape of Ulleundo which was described circle up to this, and it drawn the ridge line in the mountainous district. It has been understood that this map draw almost accurately like the port, the river, and the village, etc. as a result of the field investigation, though the island that doesn't exist in the south of the island is drawn.
This map also describes the island labelled as "Usan" about 30里 of Ulleundo on the east side, Both Mr. Bevers and Kyujangkak of Korean study center of Seoul National University admit that this island "Usan"is not a present Takeshima/Liancourt Rocks/Dokdo but the Jukdo which locates in the 2km east of Ulleundo. In a word, present Takeshima/Dokdo is not drawn in figure on this official map of 8 prefecture of Choson made by a Choson dynasty, and it is understood that "Usando" which South Korea insists to be today's Takeshima/Dokdo is actually another island.
