Description
A 2012 classified geospatial map covering 26 EU member states, Norway, Switzerland, and non-EU Balkan countries. The map provides landslide susceptibility assessments at a 1 km x 1 km resolution, developed by SCIOPS using over 100,000 georeferenced landslide events for model calibration. It classifies terrain into five susceptibility levels based on landslide frequency across seven climato-physiographic regions.
Use Cases
Train models to predict the 'susceptibility index' class (very high to very low) using underlying terrain parameter sets like slope gradient, soil parent material, and land cover.
Analyze regional risk by overlaying the classified susceptibility raster with population density or infrastructure data to identify high-priority areas.
Validate local landslide models by comparing their outputs against the Europe-wide 'confidence level map' which estimates the reliability of the susceptibility classification.
Conduct comparative studies of landslide drivers across the seven distinct 'climato-physiographic regions' defined in the dataset.
Strengths
Calibrated using a large validation set of over 100,000 georeferenced landslides from more than 22 countries.
Provides a continent-wide, standardized assessment at 1 km resolution across multiple European countries.
Includes an auxiliary 'confidence level map' to estimate the reliability of the susceptibility classifications.
Limitations
The 1 km resolution is coarse and may not capture local-scale terrain variations critical for detailed site assessment.
Semantic inconsistencies in input data layers, particularly the soil parent material map, introduce sensitivity and uncertainty.
Data is from 2012 and does not reflect recent land cover changes or landslide events, limiting current applicability.
Provenance
Source
SCIOPS, utilizing data collected by BGR and JRC from national and regional databases.
Collection Method
Spatial multicriteria evaluation (SMCE) model applied to classified slope gradient, soil parent material, and land cover parameters, calibrated with landslide inventories.
Freshness
Last updated on 2012-12-31.
Geography
Covers 26 EU member states, Norway, Switzerland, and non-EU Balkan countries (excludes Cyprus and Iceland).
The product is sensitive to the low resolution and semantic inconsistencies of input data layers. Users should consult the region-specific metadata for details on source data and classification systems.
