Detailed Mapping of Engineering Geomorphologic Classification Using Digital Elevation Model and Satellite Image
In order to obtain a detailed map of site amplification factors for strong motion prediction, the 50m-mesh engineering geomorphologic classification map is estimated using the existing 250m-mesh map, digital elevation model (DEM) and satellite image for Tsurumi ward, Yokohama, Japan. The resolution of the DEM and the image are 1m and 15m, respectively. The 50m-mesh map is estimated based on the characteristics of the indices computed from the DEM and the image for each geomorphologic unit. The estimated 50m-mesh map is compared with the manually classified map. The result shows that the 84% of the meshes are correctly classified while the accuracy in the lowland zone is relatively low.
