Outline of Final Research Achievements

The geomorphological changes are intense, and natural disasters frequently occur in the Japanese archipelago. The geomorphological analysis therein including shape measurement and change detection based on high-definition measurements are therefore essential. In this research, using terrestrial laser scanning (TLS) and related approaches, we developed a protocol including a series of procedures related to the acquisition process of high-definition topographic data and its analytical methods from the viewpoint of geomorphology. We also applied this approach to various field research subjects and developed a data sharing system for researchers regarding the acquired data and analysis tools.
