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

415,090 line-kilometres of Total Magnetic Intensity (TMI) data were acquired in 2024 by the WA Government during the Narryer survey. The raw-edited point-located data includes measurements such as raw TMI, compensated TMI, diurnal, fluxgate magnetometer, and altimeter heights. This dataset is hosted by Geoscience Australia Data and was last updated in May 2026.

Use Cases

• Geological mapping based on variations in the Earth's magnetic field from crustal rocks.
• Mineral exploration targeting based on Total Magnetic Intensity (TMI) anomalies.
• Environmental subsurface studies based on magnetic field data.
• Correcting magnetic survey data based on included diurnal variation measurements.

Strengths

• 415,090 line-kilometres of data provides substantial aerial coverage.
• Data was acquired with specified 100m line spacing and 50m terrain clearance.
• Includes multiple related measurements like raw TMI, compensated TMI, and diurnal data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Narryer survey area.
