Northern Ireland Coastal LiDAR Digital Surface Model, 2021

A Digital Surface Model derived from a complete airborne LiDAR survey of the Northern Ireland coastline conducted in 2021. The survey captured the intertidal area and extended approximately 200 meters landward of the high-water mark. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license.

Use Cases

• Modeling coastal erosion and accretion based on precise 3D surface data.
• Assessing flood risk and coastal vulnerability based on detailed elevation models.
• Planning coastal infrastructure and conservation projects based on current coastal morphology.
• Conducting change detection analysis for coastal zones based on high-resolution LiDAR data.

Strengths

• Data is derived from a complete airborne LiDAR survey of the entire Northern Ireland coastline.
• Survey coverage includes the intertidal area and extends approximately 200 meters landward.
• Dataset was last updated on 2026-03-18, suggesting active maintenance.

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.
