Northern Ireland Coastal Digital Terrain Model from 2021 LiDAR Survey

Northern Ireland's coastline was surveyed in 2021 via airborne LiDAR as part of the NI 3D Coastal Survey. The resulting Digital Terrain Model covers the intertidal zone and extends approximately 200 meters landward of the high-water mark. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license.

Use Cases

• Model coastal erosion and flooding based on precise coastal morphology data.
• Analyze intertidal zone topography based on the 200-meter landward survey extent.
• Create baseline 3D maps for coastal management and planning based on the Digital Terrain Model.

Strengths

• Data is derived from a complete airborne LiDAR survey of the Northern Ireland coastline commissioned in 2021.
• Survey coverage includes the intertidal area and extends approximately 200 meters landward of the high-water mark.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
