Northern Ireland Coastal LiDAR Digital Surface Model, 2021 Survey

A complete airborne LiDAR survey of the Northern Ireland coastline was commissioned in 2021 as part of the NI 3D Coastal Survey. The survey captured the intertidal area and extended approximately 200 meters landward of the high-water mark. This dataset is the Digital Surface Model derived from that LiDAR data, provided by OpenDataNI.

Use Cases

• Modeling coastal erosion and accretion based on precise 3D surface data.
• Assessing flood risk and coastal vulnerability based on detailed intertidal and landward topography.
• Planning coastal infrastructure and conservation projects based on current coastal morphology.
• Conducting 3D visualization and analysis of the Northern Ireland coastline.

Strengths

• Data is derived from a complete airborne LiDAR survey commissioned for the entire Northern Ireland coastline.
• Survey coverage includes the intertidal zone and extends approximately 200 meters landward of the high-water mark.
• Data is provided under the permissive OGL-UK-3.0 license.

Limitations

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