Bare Sand and Wind Metrics for Four UK Coastal Dunes, 2014-2016

Geospatial data contains values of bare sand area, modelled wind speed, aspect, and slope at a 2.5 m spatial resolution for four UK coastal dune fields. The dataset covers over 5.2 million square meters of dune area across sites in England and Wales. All values were calculated from aerial imagery and digital terrain models collected between 2014 and 2016.

Use Cases

• Statistically test the relationship between bare sand area and abiotic factors like wind speed, slope, and aspect.
• Model wind speed at 0.4 m above the dune surface using computational fluid dynamics (CFD) outputs.
• Analyze slope and aspect values derived from digital terrain models to understand dune morphology.
• Map and compare bare sand coverage across four distinct dune field locations.

Strengths

• High spatial resolution of 2.5 meters for all measured variables.
• Covers a total dune area exceeding 5.2 million square meters across four sites.
• Data derived from authoritative sources: EDINA aerial imagery and LIDAR digital terrain models.

Limitations

• Temporal coverage is limited to a single snapshot from 2014-2016, not a time series.
• Geographic scope is restricted to only four specific dune fields in England and Wales.
• The raw description does not specify column names or the internal data structure.
