Dataset of Deep-Seated Gravitational Slope Deformations and Their Associated Landforms in Friuli Venezia Giulia Region (Italy)

Deep-seated gravitational slope deformations (DGSDs) are large, slow-moving landslides that strongly influence mountain landscape evolution and slope stability. Despite their geomorphological importance, no standardized regional geospatial dataset describing DGSDs and their associated gravity-induced landforms has been available for the Friuli Venezia Giulia Region (NE Italy). In this study, a dataset including DGSDs and their gravity-induced landforms that affect the mountainous sector of the above-mentioned region is presented. The dataset was produced through the integrated interpretation of high-resolution LiDAR-derived digital elevation models, orthophotos, European Ground Motion Service (EGMS) InSAR data, landslide inventories, and uncrewed aerial vehicle (UAV)-assisted field surveys. It is distributed as a GeoPackage containing DGSD boundaries together with point, line, and polygon layers representing gravity-induced landforms, as well as an attribute table describing the geometry, morphometry, geology, auxiliary data, metadata, and associated landforms of each mapped DGSD. Its standardized and interoperable structure facilitates visualization, querying, comparison, and integration with other geospatial datasets, providing a reproducible resource for future geomorphological investigations and database updates.
