A 2021 geospatial dataset from the Bureau de Recherches Géologiques et Minières delineating areas exposed to terrain movement hazards for the commune of Cazes-Mondenard in Tarn-et-Garonne, France. It represents hazard zones used for risk analysis in the Natural Risk Prevention Plan (PPRN), based on a synthesis of calculated, modelled, and observed hazard data. The dataset includes areas protected by structures, which are considered subject to hazard.
Use Cases
- Assess land suitability for construction based on hazard intensity levels.
- Model risk scenarios for terrain movement events based on hazard probability and intensity.
- Inform regulatory zoning decisions for the Natural Risk Prevention Plan (PPRN).
- Analyze the spatial distribution of multi-hazard exposures within a commune.
Strengths
- Dataset is based on a synthesis of multiple hazard data sources, suggesting methodological rigor.
- Explicitly includes areas behind protective structures, acknowledging their potential failure.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2021-07-22 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
