| Outline of Final Research Achievements |
To advance and disseminate the geoscientific applications of high-definition topographic data acquisition methods, including laser scanning and photogrammetry, and to establish a research hub in the Asia-Oceania region, we aim to standardize the methods for obtaining high-definition spatial information, particularly in terrestrial areas. These methods include terrestrial and mobile laser scanning, and structure-from-motion multi-view stereo photogrammetry utilizing RGB, near-infrared, and thermal infrared sensors mounted on small unmanned aerial system. We have successfully systematized the methods for acquiring high-definition topographic information in land areas, with advanced discussions on the application and utilization of field surveys, ranging from efficient data acquisition methods to ideas related to academic and educational utilization. This progress has been made in conjunction with the exchange of information, taking into account the characteristics of the region.

| Academic Significance and Societal Importance of the Research Achievements |
ニュージーランドや日本をはじめ、世界各国で進めている高精細地形情報に関連した研究プロジェクトから蓄積されるデータの処理とアーカイヴ化を進展させることで、急速に高精細化する地球表層環境情報の地球科学研究における利活用の普及に貢献した。また、3次元情報の可視化による教育的活用についての実践も行い、アカデミアだけでない教育界、産業界への展開もその道筋を見出し、アジアオセアニア地域における研究拠点の礎を構築できた。
