5028 Block 4 (Northeast) Reduced Magnetic Point-Located Data

2024 Total Magnetic Intensity (TMI) data from the Narryer survey, consisting of 415,090 line-kilometres. The data was acquired by the WA Government and processed by Geoscience Australia Data to highlight subsurface geology. It has undergone multiple corrections including diurnal, geomagnetic reference field, and micro-levelling.

Use Cases

• Geological mapping based on variations in the Earth's magnetic field intensity.
• Mineral exploration targeting based on processed magnetic anomalies highlighting subsurface geology.
• Environmental studies utilizing corrected magnetic data for subsurface characterization.

Strengths

• 415,090 line-kilometres of data provides substantial spatial coverage.
• Data has undergone five specific processing reductions, including diurnal correction and micro-levelling, indicating a high level of refinement.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update was 2026-05-14.
