St-Denis-d’Oléron Natural Hazard Risk Zones for Forest Fires and Coastal Erosion

A geospatial dataset from the French Geological Survey (BRGM) defining regulated land-use zones for natural hazards in the commune of St-Denis-d’Oléron. The data categorizes areas by hazard level, such as 'red zones' where construction is prohibited and 'blue zones' where projects are subject to requirements. It was last updated on September 17, 2021.

Use Cases

• Modeling flood and erosion risk exposure based on the defined hazard zones.
• Planning urban development and construction restrictions based on the 'red' and 'blue' zone classifications.
• Assessing regulatory compliance for projects in areas not directly exposed to risks but where development could aggravate hazards.

Strengths

• Data is provided by the authoritative French Geological Survey (BRGM).
• The description provides a clear regulatory framework for interpreting the hazard zones.
• Last update date (2021-09-17) is explicitly provided.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data is specific to a single commune, which may limit broader geographic analysis.
• Freshness should be verified as the last update was in 2021.
