5028 Block 2 (Southeast) Reduced Magnetic Point-Located Data from 2024 Narryer Survey

Total Magnetic Intensity (TMI) point-located data measures variations in the Earth's magnetic field. The dataset contains 415,090 line-kilometres of aeromagnetic data from the 2024 Narryer survey in Western Australia, processed with noise compensation and geomagnetic corrections. It was acquired by the WA Government and published by Geoscience Australia.

Use Cases

• Geological mapping based on processed magnetic intensity data highlighting subsurface geology.
• Mineral exploration targeting based on magnetic anomalies in the Earth's crust.
• Environmental studies assessing magnetic field variations in a surveyed region.

Strengths

• Contains 415,090 line-kilometres of data, indicating a large-scale survey.
• Data has multiple applied reductions including diurnal correction and micro-levelling, suggesting high processing standards.
• Acquired with specified 100m line spacing and 50m terrain clearance, providing consistent spatial resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
