A Digital Surface Model derived from topographic LiDAR surveys of soft sedimentary coastlines on the north coast of Northern Ireland. Fugro collected the data in March and September 2022 to measure coastal change and recovery following major storms. The survey covers specific beaches from Curran Strand to Magilligan, with data acquired at 0.5m resolution from the intertidal zone to 10m inland.
Use Cases
- Quantifying coastal erosion and accretion based on repeat LiDAR surveys mentioned in the description
- Modeling beach recovery after storms based on pre- and post-event topographic data
- Assessing changes to soft sediment coastlines based on the comparison to a 2021 baseline survey
Strengths
- Data is directly comparable with a baseline survey from 2021, enabling change detection
- Surveys were conducted at a high 0.5m spatial resolution
- Covers multiple specific beach areas (Curran Strand, Portrush East Strand, Portstewart Strand, Downhill Beach to Magilligan)
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Survey conditions were restrictive, requiring specific tidal, weather, and daylight windows
