The NI 3D Coastal Survey commissioned a complete airborne LiDAR survey of the Northern Ireland coastline in 2021. The survey captured the intertidal area and extended approximately 200 meters landward of the high-water mark. This dataset is the Digital Surface Model derived from that LiDAR data.
Use Cases
- Model coastal erosion and accretion based on precise coastal morphology data.
- Analyze intertidal zone topography based on LiDAR-derived surface elevation.
- Assess coastal infrastructure vulnerability based on high-resolution landward elevation data.
- Create baseline maps for coastal management based on the 2021 survey snapshot.
Strengths
- Data is derived from a complete airborne LiDAR survey commissioned in 2021.
- Survey coverage includes the intertidal area and extends approximately 200 meters landward.
- Data is described as precise and accurate for current coastal morphology.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
