Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. Aeromagnetic data were compiled, merged, and levelled to produce derivative maps for each 250k-scale map sheet. The dataset includes four magnetic derivative maps per sheet, provided as PDFs, GeoTIFFs, and Geosoft grid files.
Use Cases
- Geological interpretation based on the Residual Total Magnetic Field maps.
- Mineral exploration targeting based on the Reduced-to-Pole (RTP) Magnetic Field maps.
- Structural analysis based on the First Vertical Derivative of the RTP maps.
- Edge detection of magnetic sources based on the Tilt Derivative of the RTP maps.
Strengths
- Data processing was performed over a defined period between November 2016 and March 2017.
- Four distinct magnetic derivative maps are produced for each 250k-scale map sheet.
- Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
