Comparison of erosion surface between north- and south-Abukuma mountains using summit level surface

Abstract

The purpose of this study is to compare both erosion surfaces between north- and south-Abukuma mountains. First, summit level surface data were generated (Lai et al., 2002) based on 50m grid Digital Elevation Model (DEM). The (a), (b) are summit level data (1.375km by 1.375km) and origitanl landform using 50m grid DEM, respectively. Second, elevation classification map was produced using the summit level surface data. As a result, both erosion surfaces were successfully compared on the classification map.
