Terrestrial laser scans of a 400 m x 400 m area on the Hammarryggen Ice Rise in East Antarctica. The dataset contains point clouds from 5 scan days in December 2018 and January 2019, processed to reveal snow erosion and deposition patterns. Data was collected by ENVIDAT using a Riegl VZ-6000 TLS.
Use Cases
- Model snow erosion and deposition patterns based on registered successive scans.
- Analyze surface topography changes over a 400 m x 400 m area based on multi-day point clouds.
- Validate remote sensing data using high-resolution terrestrial laser scan data.
- Study ice rise dynamics based on 1 mm and 10 cm resolution filtered surface models.
Strengths
- Scans cover 5 specific days in the 2018-2019 Austral summer, providing a temporal series.
- Data includes point clouds filtered at both 1 mm and 10 cm octree resolutions.
- Four reflectors were used over the full period, likely improving registration accuracy within their enclosed area.
Limitations
- Scans from January 2 exhibited small tilt during acquisition and are noted as having lesser accuracy.
- The coordinate system is arbitrary and not related to any global coordinate system.
- Column-level documentation is absent; field semantics must be inferred after download.
