Outline of Final Research Achievements

In this study, the research trend of HD-PCD (High-Density Point Cloud Data) was firstly reviewed, particularly regarding the existing and new methodologies of HD-PCD acquisition and analysis for physiogeographical phenomena occurring in watersheds. Based on this review, field surveys were performed in each target area using measurement equipment of HD-PCD. The acquired data were used to extract the topographic features of the watersheds and to improve the accuracy for the extraction of spatio-temporal changes therein. Furthermore, we summarized and modified the contents of the accumulated observation data for data sharing. By organizing sessions at international conferences, symposia, and outreach activities every year, we promoted the wide use of the data and tools of HD-PCD. As a result, we have shown that HD-PCD can be used in various ways, not limited to the watershed-based topographic environment.

Academic Significance and Societal Importance of the Research Achievements

研究成果をそれぞれ論文出版するとともに,国際誌における特集号を企画したり,関連するシンポジウム・ワークショップおよび大型国際会議におけるセッションの開催を継続的に実施した。これにより,HD-PCD関連の最新技術や,解析にかかる問題点,学術的・産業的適用事例の報告など,研究者間での情報共有を広く行うことができた。国外の研究者との交流も随時実施し,本研究関連の世界的な進展の方向性について相互理解を深めることができた。さらに,博物館等における企画展及びワークショップを複数開催した。これは異分野間連携を促すものであり,学際的な枠組みにおけるアウトリーチ活動に対しての本研究の影響力が評価された。
