2021 Northern Ireland Coastal LiDAR Survey Digital Terrain Model

A Digital Terrain Model (DTM) derived from a complete airborne LiDAR survey of the Northern Ireland coastline conducted in 2021. The survey captured precise data of coastal morphology, covering the intertidal area and extending 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 flood risk based on precise topographic data.
• Analyze intertidal zone morphology based on the surveyed coastal area.
• Create baseline elevation maps for coastal management planning based on the 2021 survey data.
• Integrate terrain data with hydrological models based on the high-resolution DTM.

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 is provided by an official source (OpenDataNI) under an open license (OGL-UK-3.0).

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.
