During the past decade, high-resolution and high-quality topographic data have been obtained by airborne laser swath mapping (ALSM), and light detection and ranging (LiDAR) technology. These data provide revolutionary new tools by which geomorphologists can understand earth surface processes and the influences of multiple factors on topography. Here I introduce, to Japanese geomorphologists, basic information about the airborne laser mapping technique and the National Center for Airborne Laser Mapping (NCALM) of the United States. The NCALM project has been creating new views of topography using high-resolution ALSM data. Now, we must build a public-domain ALSM database of Japan and improve geomorphology education to include techniques for ALSM data handling.
