Raw point cloud data from repeat terrestrial laser scans (TLS) tracks the initiation and development of a field of protodunes on a desert gravel interdune surface near Helga's dune at Gobabeb, Namibia. The dataset also includes concurrent measurements of wind speed from a CSAT 3D sonic anemometer and sediment transport from a Sensit device, collected on 13th September 2022. This data was produced under NERC Grant NE/R010196/1 and is associated with the British Geological Survey (BGS).
Use Cases
- Modeling protodune initiation and growth based on high-resolution topographic change data from TLS.
- Correlating sediment transport rates with wind speed measurements from the CSAT 3D sonic anemometer.
- Analyzing surface dynamics of a desert gravel interdune area based on repeat laser scans.
- Studying short-term aeolian geomorphic processes in the Namib Desert based on the coordinated sensor data.
Strengths
- Includes coordinated multi-sensor data (TLS, anemometer, sediment transport) for a single field site.
- Focuses on a specific, well-documented geomorphic event on 13th September 2022.
- Data is associated with a specific research grant (NERC Grant NE/R010196/1) and institution (British Geological Survey).
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.
- Description metadata is limited; actual data quality and completeness require manual inspection after download.
