Volcanic Bore Free Air Gravity Data for Groundwater Flow Analysis

Boreholes reaching bedrock in basalt-covered areas provide control points for Free Air gravity data interpolation. The dataset was compiled by GHD for the 'Potential Influences of Geological Structures on Groundwater Flow Systems' report, part of the DEPI SAFE Project. It is published by the Department of Energy, Environment and Climate Action and was last updated in April 2026.

Use Cases

• Interpolating Free Air gravity data based on borehole control points mentioned in the description.
• Modeling geological structures and their influence on groundwater flow systems.
• Informing resource management and entitlement projects like the Secure Allocation Future Entitlements (SAFE) Project.

Strengths

• Published under a permissive CC-BY-4.0 license.
• Compiled by a professional firm (GHD) for a specific government report.
• Available in multiple geospatial formats (SHP, GDB, TAB, etc.).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
