Unified Global Landslide Catalogue (UGLC)

Description

Abstract (En)

The Unified Global Landslide Catalog (UGLC) is a harmonized global-scale landslide inventory that integrates and standardizes all publicly available landslide datasets at global, national, and sub-national levels. It includes both point and polygonal records, each accompanied by key spatial and temporal metadata, as well as general descriptive information (e.g., trigger type, source, date, etc.).

The catalog aims to provide a consistent and ready-to-use reference for the scientific community, supporting applications such as landslide susceptibility modeling, risk assessment, and Earth system science studies. All records have been carefully processed to ensure interoperability and transparency, with detailed documentation on source attribution and spatial/temporal accuracy.

Researchers and institutions interested in contributing additional landslide data are encouraged to get in touch with:
Saverio Mancino – saverio.mancino@uniba.it
Giuseppe Amatulli – giuseppe.amatulli@yale.edu

The full codebase, processing workflows, and data specifications are openly available on GitHub at:
- UGLC point repository
- UGLC polygonal repository

Technical info (En)

The UGLC catalog is also available in GeoPackage format, divided into 105 tiles that cover the entire Earth's surface. Each tile includes a Tile_ID attribute (_i_j) for unique identification within the UGLC_tile_grid.

i (longitude step) = [0-15]
j (latitude step) = [0-7]
Empty tiles are automatically excluded from storage, ensuring optimized file management and performance.
