Bathymetric LiDAR and Orthophotography of Dundrum Bay and Carlingford Lough

OpenDataNI commissioned a pilot bathymetric LiDAR survey in 2021 as part of the NI 3D Coastal Survey. The dataset maps the nearshore areas of Dundrum Bay and Carlingford Lough, with natural colour orthophotography captured simultaneously. The data is available in HTML and JSON formats under the OGL-UK-3.0 license.

Use Cases

• Modeling coastal erosion and sediment dynamics based on bathymetric LiDAR data.
• Creating high-resolution base maps for marine spatial planning using orthophotography.
• Training machine learning models for underwater feature detection from LiDAR point clouds.
• Assessing changes in coastal morphology by comparing this survey with future or historical data.

Strengths

• Data includes both bathymetric LiDAR and natural colour orthophotography, providing complementary remote sensing modalities.
• Dataset is part of a structured regional initiative (NI 3D Coastal Survey).
• Last updated metadata indicates a recent review in March 2026.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
