RER2023: the landslide inventory dataset of the May 2023 Emilia-Romagna event - Version 1

The dataset consists of 80,997 polygons that document the landslides occurred in Emilia-Romagna, Italy, in May 2023. Landslides were manually mapped by experts using high-resolution aerial images (0.2 m resolution, RGB and near-infrared) taken shortly after the event. This landslide inventory has been designated as reference map by the Emilia-Romagna Region and the Po River Authority for the “Special Plan for interventions against situations of hydrogeological instability” (June 2024). It also serves to assist the Commission for Reconstruction during the recovery phase.

The dataset is provided in ESRI (Environmental Systems Research Institute) shapefile format and includes several attributes: polygon ID (IDC), manually classified landslide type (ClassMan), geological unit at the polygon's centroid (Lito), Green Leaf Index (GLI), percentage of deposit over Non-Forested Slopes (NFS), and reclassified landslide type after applying a harmonization algorithm (ClassNew).

Landslide classification within the ClassMan and ClassNew fields includes:

DS1=debris slide with high mobility

DS2=debris slide with low mobility

DF1=debris flow with long runout

DF2=debris flow with limited runout

RS1=fully-developed rock-block slide

RS2=incipient rock-bloc kslide

ES=earth slide

EF=earth flow.

本数据集包含80997个多边形矢量要素，用于记录2023年5月意大利艾米利亚-罗马涅（Emilia-Romagna）地区发生的滑坡事件。本次滑坡由专家依托事件发生后不久获取的高分辨率航空影像（分辨率0.2米，包含RGB与近红外波段）进行人工解译勾绘。该滑坡编录成果已被艾米利亚-罗马涅大区与波河（Po）管理局指定为2024年6月发布的《水文地质不稳定状况防治专项行动计划》的参考底图，同时可为灾后恢复阶段的重建委员会提供技术支撑。
本数据集以ESRI（Environmental Systems Research Institute，环境系统研究所）形状文件（Shapefile）格式提供，包含以下属性字段：多边形ID（IDC）、人工分类滑坡类型（ClassMan）、多边形质心处的地质单元（Lito）、绿叶指数（Green Leaf Index, GLI）、非森林边坡（Non-Forested Slopes, NFS）上的堆积物占比，以及经统一化算法重分类后的滑坡类型（ClassNew）。
ClassMan与ClassNew字段涵盖的滑坡分类类型如下：
DS1=高流动性碎屑滑坡
DS2=低流动性碎屑滑坡
DF1=长运动距离碎屑流
DF2=短运动距离碎屑流
RS1=成熟型岩块滑坡
RS2=初始型岩块滑坡
ES=土质滑坡
EF=土质流滑
