Outline of Final Research Achievements

This study aims to establish and develop the theory of Uncertainty Projected Mapping (UPM), which is a mapping method that draws a map with spatial resolution according to the variation in assessed values. Currently, hazard maps of natural disasters are being published mainly by the national and local governments, but sometimes the maps provide excessive reassurance information contrary to their objectives. Can UPM theory be applied to solve this problem? To what extent do errors in the ground model and evaluation formulas affect the results of actual hazard maps? We have identified issues for the application of the UPM theory, and have aimed to establish and develop the UPM theory.

Academic Significance and Societal Importance of the Research Achievements

現在,国や自治体を中心に自然災害に関するハザードマップの公開が進められている.しかし,ハザードレベルが相対的に低く表示される箇所で過剰な安心情報となってしまう場合がある.本課題は,マップの不確実性や信頼性をマップの解像度で表示するという考えの下,空間統計学の新しい考え方を用いることによって,新しいハザードマップの適切な表示方法について検討したものである.
