Western Australia Onshore and Marine Magnetic Intensity Grid

2005 magnetic intensity data acquired by the WA Government measures variations in the Earth's magnetic field. The processed grid has a cell size of 0.0025 degrees (approximately 266m) and units are in nanoTesla. The data is quality-checked by GA geophysicists to reveal geological structures.

Use Cases

• Map subsurface geological structures based on magnetic anomaly patterns
• Identify rock types and mineral content based on magnetic susceptibility contrasts
• Support mineral exploration and resource assessment based on processed magnetic intensity data

Strengths

• Data processed via standard methods to isolate the magnetic response of subsurface rocks
• Quality-checked by GA geophysicists to ensure fitness for purpose
• Grid cell size of 0.0025 degrees provides a specific spatial resolution

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
