5028 Block 3 (Northwest): Raw-Edited Magnetic Point-Located Data from Narryer Survey

415,090 line-kilometres of Total Magnetic Intensity data were acquired over the Narryer region in 2024 by the Western Australian Government. This raw-edited point-located dataset includes measurements of raw and compensated TMI, diurnal variations, fluxgate magnetometer readings, and altimeter heights. The data is intended for geological mapping, mineral exploration, and environmental studies.

Use Cases

• Geological mapping based on variations in the Earth's magnetic field intensity
• Mineral exploration targeting based on magnetic anomalies from crustal rocks
• Environmental studies utilizing magnetic field data
• Correcting raw magnetic survey data for diurnal variations based on the included diurnal measurements
• Integrating magnetic data with GNSS heights for precise spatial analysis

Strengths

• Survey covers 415,090 line-kilometres of data, indicating a large spatial footprint
• Data was acquired in 2024, suggesting relatively recent measurements
• Includes multiple raw and corrected measurements like compensated TMI and ellipsoidal GNSS heights

Limitations

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