Post-flood field survey of the Ahr Valley (Germany)

This repository contains Metadata associated with the report "Post-flood field survey of the Ahr Valley (Germany) - <i>Building damages and hydraulic aspects</i>" by P. Korswagen, S. Harish, J. Oetjen and D. Wüthrich (DOI: 10.4233/uuid:3cafd772-facd-4e3a-8b1a-cee978562ff1)<br><br>THIS METADATA INCLUDES: <br><b>1. Geo-referenced pictures</b> collected during a field survey of the Ahr Valley (Germany) on August 17-19th 2021.<br>Photos have been arranged based on the town were they were taken. Eight locations have been selected: Dernau, Rech, Mayschoß, Altenahr, Kreuzberg &amp; Altenburg, Brück, Insul, Schuld. Pictures are named starting with the first letter of each location.<br>Photos have been categorised into three groups: W : photos showing a watermark on a façade, H : photos identifying building damage, and M : other miscellaneous images. These characters are placed second in the picture file names.<br>Photos are numbered continuously for every location (01 to 99); this means that sequential photos were taken close to each other in space. For every location, case studies of building damage (H photos) are further grouped together with an identifying character behind an underscore space (_).<br><i>e.g.</i> 'DH01_A.jpg' contains a photo taken in Dernau (D), showing building damage (H) and belonging to case study A.<br><b>2. Georeferenced water-levels</b> measured at multiple locations in the Ahr valley, presented in the file <i>Waterlevels_Data.xlsx</i>

本仓库包含与P. Korswagen、S. Harish、J. Oetjen及D. Wüthrich所著报告《德国阿尔河谷洪水后实地勘测：建筑损毁与水力学相关维度》（DOI: 10.4233/uuid:3cafd772-facd-4e3a-8b1a-cee978562ff1）相关的元数据。

本元数据包含以下内容：
1. 地理参考照片（Geo-referenced pictures）：2021年8月17日至19日于德国阿尔河谷开展实地勘测期间采集的地理参考照片。照片按照拍摄所属城镇进行分类整理，共选定8处拍摄地点：迪尔瑙（Dernau）、莱希（Rech）、迈绍斯（Mayschoß）、阿尔滕阿尔（Altenahr）、克罗伊茨贝格与阿尔滕堡（Kreuzberg & Altenburg）、布吕克（Brück）、因苏尔（Insul）以及舒尔德（Schuld）。照片文件名以对应地点名称的首字母作为开头。
照片被划分为三大类别：W类（展示建筑立面水痕的照片）、H类（用于识别建筑损毁的照片）以及M类（其他杂项图像），上述类别标识置于文件名的第二位。
每个拍摄地点的照片均采用01至99的连续编号规则，这意味着连续编号的照片在空间位置上彼此邻近。针对每个地点的建筑损毁案例（即H类照片），还会通过文件名下划线后的标识字符进行进一步分组，例如：'DH01_A.jpg'代表拍摄于迪尔瑙（首字母D）、展示建筑损毁（H类）且属于A组案例的照片。
2. 地理参考水位数据（Georeferenced water-levels）：在阿尔河谷多个实测点位采集得到的地理参考水位数据，已整理至文件Waterlevels_Data.xlsx中。
