Post-Storm LiDAR Survey of Northern Ireland's North Coast, 2022

Fugro conducted a LiDAR survey in March 2022 to assess storm damage on soft sedimentary beaches along Northern Ireland's north coast. Data was collected at 0.5m resolution from the intertidal zone to 10m inland for areas including Curran Strand and Portstewart Strand. A second survey in September 2022 measured coastal recovery, with data provided by the Government Digital Service under an OGL-UK-3.0 license.

Use Cases

• Quantifying coastal erosion and accretion based on pre- and post-storm LiDAR surveys mentioned in the description
• Modeling sediment transport and beach recovery patterns based on repeated topographic surveys
• Assessing the impact of specific storm events (Dudley, Eunice, Franklin) on soft sediment coastlines
• Creating high-resolution digital surface models for coastal zone management based on the 0.5m resolution data

Strengths

• Data is directly comparable with a baseline survey from 2021, enabling change detection
• Surveys were conducted under strict conditions (2 hours either side of Low Water, clear conditions) to ensure consistency
• Multiple file formats (KML, GeoJSON, ESRI SHAPE, CSV) are available for different analysis tools

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
• The survey was restrictive, requiring daylight and specific sun angles, which may limit temporal coverage
