Repeat gully terrestrial laser scanners data for geomorphic change detection and estimatin

Upper Burdekin and Bowen catchments in Australia are covered by terrestrial laser scanner scans and derived 5 cm digital elevation models collected between 2016 and 2019 for four paired gully sites. The dataset, part of the NESP TWQ 2.1.4 project managed by CSIRO, includes DEMs of difference used to estimate changes in gully volume. Data collection was performed annually at the end of the wet season using a RIEGL VZ400 scanner, with registration errors typically less than 1 cm.

Use Cases

• Detecting geomorphic change over time based on repeated terrestrial laser scanner scans.
• Estimating volumes of erosion and deposition based on DEMs of difference.
• Monitoring the effectiveness of gully remediation treatments based on paired Control/Treatment site data.
• Analyzing high-resolution (5 cm) topographic changes in gully headcuts and their immediate vicinity.

Strengths

• Data spans up to 4 years of repeated annual surveys between 2016 and 2019, providing a temporal series.
• High-resolution 5 cm gridded digital elevation models derived from point cloud data.
• Scanner registration was performed with errors typically less than 1 cm, indicating high positional accuracy.
• Includes data from four paired Control/Treatment gully sites, allowing for comparative analysis.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific Australian catchments studied.
