Airborne Gravity Gradiometry Quality Control Metrics for Survey Assessment

Geoscience Australia presents a series of standard quality control metrics for airborne gravity gradiometry (AGG) field data. The metrics form the basis of the agency's technical specifications and were presented at the 2025 Australasian Exploration Geoscience Conference. This dataset is intended to provide consistency for assessing AGG surveys used in mineral, hydrocarbon, and geothermal energy exploration.

Use Cases

• Evaluating the quality of AGG survey data based on standardized metrics.
• Comparing consistency across different AGG surveys and systems as mentioned in the description.
• Developing or auditing technical specifications for AGG data acquisition.
• Assessing the suitability of AGG data for exploration targeting in minerals, hydrocarbons, or geothermal energy.

Strengths

• Developed by Geoscience Australia, a national geoscience agency.
• Metrics are designed to provide consistency across different surveys and systems.
• Addresses a stated need for public quality control standards in a growing data acquisition field.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is PDF, which may require extraction for computational use.
