5028 Block 4 (Northeast) Raw-Edited Magnetic Point-Located Data

415,090 line-kilometres of raw-edited Total Magnetic Intensity (TMI) data acquired in 2024 by the WA Government over the Narryer survey area. The dataset includes raw and compensated TMI measurements, diurnal variations, fluxgate magnetometer readings, and raw altimeter and GNSS heights. This line dataset was collected at 100m line spacing and 50m terrain clearance for geological mapping and mineral exploration.

Use Cases

• Geological mapping based on variations in the Earth's magnetic field intensity.
• Mineral exploration targeting based on magnetic anomalies associated with rock magnetism.
• Environmental studies of subsurface geology based on crustal magnetic field data.
• Correcting magnetic survey data for diurnal variations based on the included diurnal measurements.
• Integrating precise GNSS and altimeter heights for spatial analysis of magnetic features.

Strengths

• Contains 415,090 line-kilometres of data, indicating a large-scale survey.
• Includes both raw and compensated Total Magnetic Intensity (TMI) measurements.
• Provides multiple height measurements (raw altimeter and ellipsoidal GNSS) for spatial accuracy.

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 Narryer survey area in Western Australia.
