A 2021 pilot survey commissioned for the NI 3D Coastal Survey captured bathymetric LiDAR data and simultaneous natural colour orthophotography. The data maps the nearshore areas of Dundrum Bay and parts of Carlingford Lough in Northern Ireland. It is provided by the Government Digital Service under the OGL-UK-3.0 license.

Use Cases

• Model coastal erosion and sediment transport based on the bathymetric LiDAR survey.
• Classify nearshore land cover and habitats using the natural colour orthophotography.
• Create 3D coastal models by integrating the LiDAR and orthophoto data.
• Analyze changes in coastal morphology by comparing this survey to future or historical data.

Strengths

• Data was captured simultaneously, ensuring temporal alignment between LiDAR and orthophoto layers.
• The survey is part of a structured government initiative (NI 3D Coastal Survey).
• Available in multiple geospatial formats including GEOJSON, CSV, and JSON.

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.
• Last update date is unknown; freshness unverified.
