Dataset: Structural building damage mapped with use of remote sensing in the Ahr valley

The following vector layer (ESRI Shapefile) encompasses 19507 polygons (buildings) in the Ahr Valley, Rhineland-Palatinate, Germany, having as attribute the structural damage grades, collected in the aftermath of the extreme event of July 2021.The polygons were extracted from OpenStreetMap (OpenStreetMap contributors, 2022). Only the geometries were used.The damage grades assessment to each building followed the classification scheme by Maiwald & Schwarz (2019) and was accomplished by visual assessment.

以下矢量图层（ESRI Shapefile）涵盖德国莱茵兰-普法尔茨州阿尔河谷区域的19507个多边形要素（代表建筑物），其属性字段为结构损毁等级，数据采集于2021年7月极端灾害事件的灾后阶段。该多边形数据提取自开放街道地图（OpenStreetMap，开放街道地图贡献者，2022），仅使用了其中的几何信息。每栋建筑物的损毁等级评估遵循Maiwald与Schwarz（2019）提出的分类方案，并通过目视解译完成。
