Bathymetric LiDAR And Orthophotography For Dundrum Bay And Carlingford Lough

A pilot bathymetric LiDAR survey commissioned in 2021 as part of the NI 3D Coastal Survey. The dataset maps the nearshore areas of Dundrum Bay and Carlingford Lough and includes simultaneously captured Natural Colour Orthophotography. It is provided by the Government Digital Service under an OGL-UK-3.0 license.

Use Cases

• Modeling coastal erosion and sediment transport based on bathymetric elevation data.
• Creating habitat maps for marine conservation based on combined bathymetric and optical imagery.
• Developing baseline data for coastal infrastructure planning from the 3D survey.
• Calibrating and validating remote sensing algorithms using the paired LiDAR and orthophoto data.

Strengths

• Data includes two complementary sensor types: bathymetric LiDAR and Natural Colour Orthophotography.
• Survey was conducted as part of a structured 3D Coastal Survey program.
• Data is 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.
