BUREAU DE RECHERCHES GÉOLOGIQUES ET MINIÈRES provides a surface representation of areas below the 4.20-meter NGF elevation level on part of the Charente-Maritime coastline. The dataset was constructed by horizontal projection based on the RGE alti reference data. It was last updated on September 17, 2021.
Use Cases
- Map coastal flood risk zones based on the 4.20-meter NGF elevation threshold.
- Analyze low-lying terrain for urban planning based on the surface representation.
- Model sea-level rise impacts on specific coastal areas based on the elevation data.
Strengths
- Dataset is based on the authoritative RGE alti reference data.
- Specific elevation threshold of 4.20 meters NGF is defined.
- Geographic scope is clearly defined as the Charente-Maritime coastline.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2021-09-17 00:00:00; freshness should be verified.
