Outline of Final Research Achievements

Detection of spatial patterns is an important method in quantitative geography. There have been developed numerous methods for detecting spatial patterns efficiently and objectively. There exist, however, a wide variety of spatial patterns, not all of which can be captured by existing methods. To resolve the problem, this study proposed a new general procedure for detecting spatial patterns. The procedure is based on a statistical framework, which enables us to treat a wide variety of spatial patterns.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した地理パターンの抽出方法は,極めて広範な地理解析に適用可能であり.既存手法の改良や新たな手法の開発などに大きく寄与することが出来る.また,地理解析は地理現象を対象とする様々な研究分野(例えば疫学や林学など)の研究者が行うことから,研究領域という意味においても広範な貢献が期待できると考えている.
