Yukon Aeromagnetic Maps for NTS 105D, 2016-2017 Reprocessing

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 Residual Total Magnetic Field, Reduced-to-Pole, and vertical and tilt derivative maps provided as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral prospectivity mapping based on magnetic derivative maps
• Geological structure interpretation based on Reduced-to-Pole Magnetic Field data
• Regional geophysical analysis based on levelled, multi-resolution compiled data

Strengths

• Data was reprocessed and levelled for consistency across map sheets
• Four distinct magnetic derivative products are provided for each map
• Files are available in three standard geospatial formats (PDF, GeoTIFF, Geosoft grid)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
