Ortho: Post-Storm Coastal LiDAR and Orthophotography of Northern Ireland

Northern Ireland's north coast was surveyed using LiDAR and orthophotography in March and September 2022. Fugro was commissioned to capture data from Curran Strand to Magilligan to assess damage and recovery from storms Dudley, Eunice, and Franklin. The data, provided by OpenDataNI, is directly comparable to a baseline 2021 survey.

Use Cases

• Quantifying coastal erosion and accretion based on repeat LiDAR surveys.
• Monitoring beach recovery post-storm based on time-series orthophotography.
• Analyzing intertidal zone changes based on data collected 2 hours either side of low water.
• Modeling sediment transport dynamics based on high-resolution (0.5m) topographic data.

Strengths

• Data is directly comparable between March and September 2022 surveys and a 2021 baseline.
• Surveys captured the intertidal area to 10m inland at a 0.5m resolution.
• Collection followed strict environmental conditions (clear, below 6000ft, suitable sun angle).

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.
• Survey windows were restrictive, limited to daylight hours around low tide.
