2021 Northern Ireland Coastal Bathymetric LiDAR and Orthophotography

A pilot bathymetric LiDAR survey mapped nearshore areas of Dundrum Bay and Carlingford Lough in 2021. Natural colour orthophotography was captured simultaneously as part of the NI 3D Coastal Survey. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license.

Use Cases

• Model coastal erosion and sediment transport based on bathymetric LiDAR data.
• Create detailed habitat maps for marine conservation using orthophotography.
• Develop 3D terrain models for coastal engineering projects from the survey data.
• Analyze nearshore water depth and topography for navigation safety assessments.

Strengths

• Data includes two complementary remote sensing modalities: bathymetric LiDAR and orthophotography.
• Survey was conducted as a pilot project for the NI 3D Coastal Survey, suggesting a structured data collection effort.
• Dataset is licensed under OGL-UK-3.0, which permits open use and adaptation.

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