Historical shoreline analysis for the entire Northern Ireland coastline, derived from Ordnance Survey maps and aerial imagery. Ulster University produced this dataset using the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics at 25-meter intervals. The data visualizes shoreline change and assesses historical rates of change for any coastal stretch.
Use Cases
- Calculate coastal erosion rates based on Net Shoreline Movement (NSM) and End Point Rate (EPR) statistics.
- Identify areas of shoreline retreat or accretion using spatially displayed rate-of-change data.
- Model long-term shoreline dynamics using Linear Regression Rate (LRR) and Weighted Linear Regression Rate (WLR) statistics.
- Support coastal management decisions with a historical analysis spanning annual to decadal time periods.
Strengths
- Analysis covers the entire Northern Ireland coastline.
- Derived from historical Ordnance Survey maps and aerial imagery dating back to the early 1800s.
- Rate-of-change statistics are calculated at 25-meter intervals.
- Includes multiple statistical measures: NSM, SCE, EPR, LRR, and WLR.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to uk_data.
