Low Elevation Areas of the Charente-Maritime Coastline at 3.60 Meters

A geospatial surface representation of areas at or below the 3.60-meter NGF elevation benchmark along part of the Charente-Maritime coastline. The dataset was created by the Bureau de Recherches Géologiques et Minières using horizontal projection based on the RGE Alti reference elevation model. It was last updated on September 17, 2021.

Use Cases

• Model coastal inundation zones based on the defined 3.60-meter elevation threshold.
• Plan land use and development based on identified low-lying areas.
• Assess flood risk and vulnerability for infrastructure along the coastline.

Strengths

• Based on the authoritative RGE Alti elevation reference model.
• Provides a specific, defined elevation threshold (NGF 3.60 m) for analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-09-17 00:00:00; freshness should be verified.
• Spatial coverage is limited to a part of the Charente-Maritime coastline.
