建物群の被災可能性推計・地図表示による震災対応支援システムの構築
広域に分布する多数の建物の被災可能性を簡易に推計し、地震発生から概ね10分程度後にWebマップで分かりやすく表示するシステムを構築した。気象庁の推計震度分布を地理院タイルで可視化、震度と対象建物の属性から被災可能性を推計して大中小に区分し、建物の空間分布と表示縮尺に応じた適切な領域区分毎に集計し、円グラフで表示する。これにより被害の全体像から各地の細部までシームレスに把握でき、初動対応の迅速化・効率化に役立つ。
Construction of Earthquake Disaster Response Support System with Estimation and Mapping of the Possibility of Damage to Buildings
We built a system that simply estimates the possibility of damage to many buildings distributed over a wide area, and displays it on a web map in an easy-to-understand manner in about 10 minutes after the earthquake. The system visualizes the estimated seismic intensity distribution of Japan Meteorological Agency, estimates the possibility of damage from the seismic intensity and the attributes of the target building, divides the possibility into large, medium and small, and aggregates for each appropriate area segmentation according to the spatial distribution of the building and the display scale, and displays as a pie chart. This makes it possible to seamlessly grasp the overview of damage and the details of each area, which helps to speed up and improve the efficiency of initial response.
