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. For a detailed explanation of the dataset, its attributes, and the harmonization methodology, please refer to the accompanying paper.
