Post-Storm Coastal LiDAR Survey of Northern Ireland, 2022

A post-storm LiDAR survey commissioned in March 2022 covered soft sedimentary areas along the north coast of Northern Ireland, including Curran Strand and Portstewart Strand. The survey was repeated in September 2022 to measure coastal recovery, with data acquired at 0.5m resolution from the intertidal area to 10m inland. This Digital Surface Model is provided by OpenDataNI under the OGL-UK-3.0 license.

Use Cases

• Quantifying coastal erosion and accretion based on pre- and post-storm LiDAR data comparisons.
• Modeling sediment transport and beach recovery dynamics after extreme weather events.
• Assessing storm damage to soft sedimentary coastlines using high-resolution topographic change detection.

Strengths

• Data is directly comparable with a baseline survey from 2021, enabling precise change analysis.
• Surveys were conducted under specific, controlled conditions (e.g., 2 hours either side of Low Water) to ensure data consistency.
• Data was collected at a high 0.5m spatial resolution.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The survey's restrictive flight conditions (daylight, clear weather) may limit temporal coverage.
