5028 Block 1 (Southwest): Raw-Edited Magnetic Point-Located Data from 2024 Narryer Survey

2024 magnetic survey data from the Narryer region in Western Australia, consisting of 415,090 line-kilometres of measurements. The dataset includes raw and compensated Total Magnetic Intensity (TMI), diurnal variations, fluxgate magnetometer readings, and altimeter heights. It was acquired by the WA Government and published by Geoscience Australia.

Use Cases

• Geological mapping based on variations in the Earth's magnetic field intensity.
• Mineral exploration targeting based on the magnetism of crustal rocks.
• Environmental subsurface studies utilizing magnetic anomaly data.
• Correcting magnetic survey data for diurnal variations using the included diurnal measurements.

Strengths

• Large-scale aerial survey covering 415,090 line-kilometres.
• Includes multiple raw and processed magnetic measurements such as raw TMI, compensated TMI, and diurnal data.
• Acquired with specified survey parameters: 100m line spacing and 50m terrain clearance.

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 survey block in Western Australia.
