NESP TWQ 2.1.4: RTK GPS Survey of Remediated Gullies in GBR Rangelands, 2017-2018

CSIRO's NESP Project 2.1.4 collected RTK GPS survey data from April 2017 to March 2018 for five paired control and treatment gully sites in Great Barrier Reef rangelands. The dataset includes shapefiles with point data for features like headcuts and cross-sections, with attributes for location, accuracy, and survey metadata. Monitoring is part of a project evaluating gully remediation's impact on erosion and downstream water quality.

Use Cases

• Assessing gully morphology changes based on high-precision GPS survey points.
• Comparing erosion rates between treated and untreated sites using the BACI monitoring design.
• Modeling sediment transport and water quality impacts from gully features like headcuts and cross-sections.
• Validating remote sensing or other survey data against ground-truthed RTK GPS measurements.

Strengths

• Data collection uses RTK GPS with specified horizontal (+/- 12mm) and vertical (+/- 15mm) accuracy tolerances.
• Covers five distinct paired monitoring sites, providing a basis for controlled comparison.
• Includes multiple survey point types (e.g., reference markers, cross sections, instrumentation locations).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic/temporal bias inherent to the specific project sites and 2017-2018 period.
