title: Inventory of shallow landslides triggered by extreme precipitation in July 2023 in Beijing, China

description: This RLBJ inventory describes the event landslide inventory map produced to record the hazard effects of the extreme rainfall that occurred in Beijing, China, in July 2023. 
From July 29, 2023 to August 2, 2023, affected by the residual circulation of Super Typhoon Doksuri, a rare extreme rainfall event occurred in Beijing. The average precipitation across the city reached 331 mm over 83 hours. The maximum 83-hour cumulative precipitation recorded by the meteorological station was 744.8 mm. The rainfall center was located at the mountainous western areas of Beijing.
The RLBJ presented here is the result of extensive remote sensing analysis for the area most affected by the intense rainfall, covering approximately 3,250 square kilometers. The area of interest covers all mountainous areas within the Fangshan and Mentougou Districts, and the mountainous areas in the southwest of Changping District and the northwest of Haidian District in Beijing.
The inventory includes 15,383 landslide records across the mountainous western areas of Beijing, indicating an average density of about 4.7 landslides per square kilometer. The maximum landslide density in the study area reached 120 per square kilometer. The total area of all identified landslides is 19.3 square kilometers, representing 0.59% of the area of interest. The area of an individual landslide ranges from approximately 20 to 120,000 square meters.

This repository stores:
1. A map package of the final inventory, named “RLBJ_v1.0.mpk”, including 5 layers: 
(1) A point shapefile of the landslide inventory, named “Point_RLBJ”
(2) A polygon shapefile of the landslide inventory, named “Polygon_RLBJ”
(3) A polygon shapefile of the administrative boundaries of Beijing, named “BJ_Boundary”
(4) A polygon shapefile of the rainfall distribution map for Beijing, named “Rainfall”
(5) A raster TIFF layer of the Digital Elevation Model (DEM) for Beijing, named “Terrain”
The .mpk file can be opened with ArcGIS software and saves the results after visualization processing.

2. A compressed file, named “RLBJ_v1.0_shapefiles.rar”, containing all original shapefiles:
(1) A point shapefile of the landslide inventory
(2) A polygon shapefile of the landslide inventory
(3) A polygon shapefile of the administrative boundaries of Beijing
(4) A polygon shapefile of the rainfall distribution map for Beijing
(5) A raster TIFF layer of the Digital Elevation Model (DEM) for Beijing
The contents of the shapefile in the compressed package are essentially the same as the corresponding layer in the map package. These shapefile files retain all attribute information and can be read in various GIS software platforms.

3. A PDF document, named “Field logs.pdf”, summarizing field survey photos:
This document summarizes the photos taken during the field verification process of landslides in the dataset. These photos cover a total of 403 landslides. The document also includes a comparison of field observation records and remote sensing interpretation records. 
4. A PDF document, named “Metadata.pdf”, providing necessary explanations for attribute classification in the dataset
