NCERM: National Coastal Erosion Risk Management Map with 2005-2105 Projections

The National Coastal Erosion Risk Management map shows the spatial coastal baseline split into 'frontages' with consistent cliff and defence characteristics. It provides an up-to-date benchmark of erosion extents and rates for three periods from a base date of 2005: Short Term (0-20 years), Medium Term (20-50 years), and Long Term (50-100 years). The dataset, from the Government Digital Service, includes predictions for 'No Active Intervention' and 'Shoreline Management Plan 2 Policies' scenarios with 5-95%ile confidence ranges.

Use Cases

• Modeling coastal erosion risk over 100-year horizons based on the defined Short, Medium, and Long Term periods.
• Comparing erosion outcomes under 'No Active Intervention' versus 'Shoreline Management Plan 2 Policies' scenarios.
• Planning coastal defence strategies based on frontage-specific cliff behaviour and defence characteristics.
• Assessing the spatial variability of erosion using the 5-95%ile confidence range data attributes.

Strengths

• Provides a consistent, up-to-date spatial baseline for coastal erosion risk assessment.
• Includes erosion predictions for three distinct time periods spanning 100 years from a 2005 base date.
• Offers data for two policy scenarios with cumulative distance metrics and specified confidence levels (50%ile extents, 5-95%ile range attributes).

Limitations

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