Description :
This paper proposes a quantitative method to classify landforms using 4 morphometric parameters from DEM-derived thematic raster maps of slope and topographic openness. The raster maps of slope and topographic openness were constructed for Northeast Honshu, from 50-m DEMs. A supervised landform classification for Northeast Honshu using the knowledge from the training areas revealed a ladder geomorphological structure composed of high mountains, ranges and volcanoes. The structure reflects the magmatic plumbing system from the upper mantle to the crust of the Northeast Honshu arc.
