Historical Shoreline Evolution of Normandy, France from 1947 to 2010 at 1:2500 Scale

1947 to 2010 shoreline change data for the Basse-Normandie region of France, digitized from orthorectified aerial photographs. The dataset includes trend histograms and synthesized linear information for homogeneous sectors, produced by the Bureau de Recherches Géologiques et Minières (BRGM) in collaboration with CEREMA, DREAL, and ROLNP. It is provided as a WMS service.

Use Cases

• Modeling coastal erosion and accretion trends based on the digitized historical shoreline positions.
• Analyzing qualitative trend information for homogeneous coastal sectors as described in the synthesized linear data.
• Visualizing multi-decadal shoreline change using the provided WMS layers and trend histograms.

Strengths

• Covers a 63-year time span from 1947 to 2010.
• Provides data at a detailed 1:2500 scale.
• Includes multiple survey years (1947, 1977, 1982, 1991-92, 2001, 2010).

Limitations

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