Historical shoreline positions for the Northern Ireland coastline, derived from Ordnance Survey maps and aerial imagery. Ulster University analyzed the data using the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics at 25-meter intervals. The dataset provides a dynamic picture of coastal change from the early 1800s to 1906.
Use Cases
- Calculate rates of shoreline change based on Net Shoreline Movement (NSM) and End Point Rate (EPR) statistics.
- Identify areas of coastal retreat or accretion using spatially displayed rate-of-change data.
- Model long-term coastal dynamics using Linear Regression Rate (LRR) and Weighted Linear Regression Rate (WLR) statistics.
- Visualize historical shoreline geometry changes over annual to decadal time periods.
Strengths
- Analysis covers the entire Northern Ireland coastline.
- Rate-of-change statistics were calculated at 25-meter intervals.
- Derived from Ordnance Survey maps and aerial imagery spanning from the early 1800s.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
