A Digital Terrain Model (DTM) created from a LiDAR survey commissioned by Fugro in March 2022. The survey covers soft sedimentary areas along the north coast of Northern Ireland, including Curran Strand and Portstewart Strand, to assess coastal change following storms Dudley, Eunice, and Franklin. Data is provided in a format consistent with a 2021 baseline survey to enable change detection.
Use Cases
- Quantifying coastal erosion based on post-storm LiDAR elevation data.
- Modeling sediment transport and beach morphology changes using the Digital Terrain Model.
- Assessing storm damage to sandy beaches along the surveyed coastline.
- Comparing pre-storm (2021) and post-storm (2022) coastal topography for change analysis.
Strengths
- Data is structured for direct comparison with a baseline survey from 2021.
- Survey was commissioned specifically to assess damage from three named storms (Dudley, Eunice, Franklin).
- Covers four specified coastal areas: Curran Strand, Portrush East Strand, Portstewart Strand, and Downhill Beach to Magilligan.
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.
