Map visualisation service (WMS) of the dataset: Awareness of the reference marine submersi

A 2017 report on marine flooding was delivered to six coastal municipalities based on updated risk knowledge. This geospatial layer visualizes the reference marine submersion hazard for the eastern part of the TRI St-Malo-Baie-du-Mont-St-Michel territory in the Ille-et-Vilaine department. The data originates from studies under the 2015 Floods Directive and was last updated on April 7, 2023.

Use Cases

• Visualize coastal flood risk zones based on the referenced hazard maps.
• Assess the impact of updated topography and protection works on flood modeling.
• Support municipal planning for the six named coastal communities.
• Integrate hazard data into broader Flood Risk Management Plan (PGRI) analyses.

Strengths

• Data is based on updated 2017 knowledge of topography and protection works.
• Hazard mapping is linked to the official 2015 Floods Directive studies.
• Spatial coverage is explicitly defined for a specific French coastal territory.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided only as a WMS service, limiting direct analysis of underlying features.
