5028 Block 4 (Northeast) reduced radiometric point-located data was acquired in 2024 by the WA Government. The dataset consists of 415,090 line-kilometres of gamma-ray spectrometric data collected at 100m line spacing and 50m terrain clearance. It is processed using methods like NASVD filtering and tie-line levelling to highlight concentrations of potassium, uranium, and thorium.
Use Cases
- Geological mapping based on natural gamma-ray variations from potassium, uranium, and thorium.
- Mineral exploration targeting based on processed radioelement concentrations.
- Environmental studies and baseline radiation mapping based on corrected radiometric data.
Strengths
- 415,090 line-kilometres of data provides substantial aerial coverage.
- Data was acquired in 2024, suggesting relatively recent measurements.
- Processing includes advanced corrections like NASVD filtering and tie-line levelling.
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 data_gov_au, being specific to Western Australia.
