『대동여지도』 도로 방점 연구

Abstract

This study verifies and analyzes the existing hypothesis on the Bangjeom(傍點) of the “Daedongyeojido(大東輿地圖)” among the old maps of the Joseon Dynasty. The total length of the roads in the “Daedongyeojido” is about 95,800 ri(里) (about 44,000 kilometers). If the road network is reconstructed by route, it is organized into a total of 1,473 sections, of which 1,040 sections are routes with Bangjeoms, 73 sections are routes with some Bangjeoms, and 360 sections are routes without Bangjeoms. There are a total of 2,185 nodes, with 335 administrative centers(邑治) and 1,850 other intersections. Comparing the distance between Bangjeoms and map’s distances, the total distance of sections with Bangjeoms is 69,500 ri, while the map’s distance is 65,794 ri, which is about 6% shorter than the map’s distance. There are several reasons for the difference in Bangjeom spacing: (1) Reflects the vertical and horizontal curvature of the road, (2) the effect of reducing the distance when expressing roads in a straight line rather than expressing roads with bends, (3) the reflection of Jijiri(地理志)’s road information. (4) the error caused by rounding the actual distance to a distance of 10 ri for Bangjeom expression, (5) the error in the location information of the geographic information expressed in the 10-ri grid map, and (6) the location error problem of “Daedongyeojido”. Some sections have adjusted point spacing to reflect terrain undulations and horizontal bends in the road, but this does not appear to be a typical pattern. About 25% of the sections have no Bangjeoms, and about 7% of the sections have some Bangjeoms. The sections with no Bangjeoms are (1) connections between towns that are not adjacent to each other, (2) in Gangwon-do and Hamgyong-do provinces where the terrain is rugged, and (3) on various side roads(捷路). Finally, the term “road equidistant points(道路等距分點)” is proposed instead of “Bangjeom(傍點)”.
