Footprint: 2021 Bathymetric LiDAR Survey of Dundrum Bay and Carlingford Lough

A pilot bathymetric LiDAR survey commissioned in 2021 as part of the NI 3D Coastal Survey. This dataset maps the nearshore areas of Dundrum Bay and Carlingford Lough, with natural colour orthophotography captured simultaneously. The data is provided by the Government Digital Service under the OGL-UK-3.0 license.

Use Cases

• Model coastal erosion and sediment transport based on bathymetric elevation data.
• Create habitat maps for marine conservation based on combined bathymetry and orthophotography.
• Develop nautical charts for safe navigation in the surveyed bays and lough.
• Train machine learning models for underwater feature detection using the point cloud and imagery data.

Strengths

• Data includes simultaneous capture of bathymetric LiDAR and natural colour orthophotography.
• Available in multiple geospatial formats including ESRI SHAPE, GEOJSON, and KML.
• Commissioned as part of a structured 3D coastal survey program.

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.
