Historical Coastline Evolution in Lower Normandy from 1947 to 2010

Historical coastline positions for Lower Normandy, France, digitized from aerial photographs for six distinct time periods between 1947 and 2010. The project was a collaboration between the ROLNP and DREAL Basse-Normandie, using a methodology developed by CEREMA. The data is provided as a WMS service representing the coastline at a 1/2500 scale.

Use Cases

• Modeling coastal erosion rates based on historical shoreline positions.
• Analyzing long-term coastline evolution from digitized aerial photography.
• Validating coastal change simulations against multi-temporal ground truth data.

Strengths

• Covers six distinct time periods spanning over 60 years (1947 to 2010).
• Based on a consistent methodology for shoreline extraction from orthorectified aerial photos.
• Provides a detailed 1/2500 scale representation of the coastline.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
