Vicdessos municipality's geographical data for its natural hazard prevention plan (PPRN), part of the national French risk prevention framework. The data standard is defined by COVADIS for homogeneous storage of regulatory maps, hazard documents, and issue maps related to major risks. The dataset was last updated by the Bureau de Recherches Géologiques et Minières on September 16, 2021.

- Mapping intensity levels of specific natural hazards like floods or avalanches referenced in the hazard documents.
- Identifying critical infrastructure and assets at risk using the maps of issues annexed to the plan.
Strengths
- Based on a standardized national data model (COVADIS) for risk prevention plans.
- Covers eight main natural hazards defined by French law, including floods, earthquakes, and forest fires.
- Includes three distinct categories of information: regulatory zoning, hazard mapping, and issue identification.
