Ortho: Natural Colour Orthophotography and Bathymetric LiDAR for Northern Ireland Coast

A 2021 pilot survey mapped the nearshore areas of Dundrum Bay and Carlingford Lough in Northern Ireland. It includes bathymetric LiDAR data and natural colour orthophotography captured simultaneously. The dataset is published by OpenDataNI under the OGL-UK-3.0 license.

Use Cases

• Generate high-resolution coastal terrain models based on the bathymetric LiDAR survey.
• Analyze shoreline change and sediment transport using the orthophotography and LiDAR data.
• Train computer vision models for coastal feature detection using the natural colour orthophotography.
• Support marine spatial planning and habitat mapping for the surveyed Northern Irish coastal areas.

Strengths

• Data includes simultaneous capture of LiDAR and orthophotography, likely ensuring temporal alignment.
• Dataset was last updated in March 2026, suggesting active metadata management.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific pilot survey areas in Northern Ireland.
