Northern Ireland Coastal Digital Terrain Model from 2021 LiDAR Survey

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

Use Cases

• Modeling coastal erosion and sediment transport based on precise terrain elevation.
• Assessing flood risk and inundation scenarios based on the high-resolution intertidal and landward terrain data.
• Planning coastal infrastructure and conservation projects based on current coastal morphology.
• Conducting 3D visualization and analysis of the Northern Irish coastline based on the DTM.

Strengths

• Data is derived from a complete airborne LiDAR survey commissioned in 2021, providing a contemporary snapshot.
• Survey coverage includes the intertidal zone and extends approximately 200 meters landward of the high-water mark.
• Data is provided under the OGL-UK-3.0 license, facilitating open use.

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.
