Abstract
This study is aimed to clarify the distribution chracteristics of marine terraces and extract the specific surface at Gampo-eup, Gyeongju city on the map of 1:5,000 using GIS. The effects and problems occurred on the process of using GIS were investigated for the research of marine terrace. The longitudinal profile analysis was carried out along the 12 sections on the geomorphic surfaces of the study area, and actually High higher surface(HH-surface) was found over 100m a.s.l., which has not been reported till now. And the occupancy rate could be calculated by substitution on the height between 4m and 87m a.s.l. for each mean slope degree
1:5,000 수치지형도를 GIS로 처리하여 해안단구가 모식적으로 분포하는 경북 경주시 감포읍 일대의 지형면 분포특색을 조사하고, 지형면을 추출하였다. 이 과정에서 해안단구 지형연구에 GIS tool의 유용성과 문제점을 검토하였다. 12 지점에서의 해안단구 종단면에 대하여 종단면분석을 행하여 한국 남부 해안에서는 보고된 바 없는 해발고도 100m 이상인 고고위면을 확인하였다. 또한, 실측으로 얻은 지형면 분포가능범위인 평균경사도
