Northern Ireland Coastal Digital Surface Model from 2021 LiDAR Survey

A 2021 airborne LiDAR survey captured the Northern Ireland coastline, including the intertidal area and extending approximately 200 meters landward of the high-water mark. This dataset is the Digital Surface Model derived from that survey, providing data on coastal morphology. The data is provided by OpenDataNI under the OGL-UK-3.0 license and was last updated in March 2026.

Use Cases

• Modeling coastal erosion and accretion based on precise surface elevation data.
• Assessing flood risk and planning coastal defenses based on the 200-meter landward coverage.
• Analyzing intertidal zone morphology and habitat mapping based on the surveyed area.
• Creating 3D visualizations and simulations of the Northern Ireland coastline.

Strengths

• Derived from a complete airborne LiDAR survey commissioned for the NI 3D Coastal Survey.
• Covers the intertidal area and extends approximately 200 meters landward of the high-water mark.
• Data is provided by the authoritative source OpenDataNI.

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 coastline survey.
