2021 Northern Ireland Coastal LiDAR Digital Surface Model

OpenDataNI provides a Digital Surface Model derived from a 2021 airborne LiDAR survey of the Northern Ireland coastline. The survey captured the intertidal area and extended approximately 200 meters landward of the high-water mark. This dataset offers precise and accurate data on current coastal morphology.

Use Cases

• Model coastal erosion and flood risk based on precise topographic data.
• Analyze intertidal zone morphology based on LiDAR-derived surface models.
• Create 3D visualizations of the coastline for planning and environmental monitoring.
• Assess changes in coastal landforms over time when compared with historical surveys.

Strengths

• Data is described as 'precise and accurate' for coastal morphology.
• Spatial coverage is defined, including the intertidal area and 200 meters landward.

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.
