Yukon Aeromagnetic Survey Reprocessing for NTS 105O

Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. Aeromagnetic data were compiled and merged to produce four derivative maps per 250k-scale map sheet. The maps are provided as PDFs, GeoTIFFs, and Geosoft grid files by the Government of Yukon.

Use Cases

• Mineral exploration targeting based on magnetic derivative maps like Reduced-to-Pole Magnetic Field.
• Geological structure mapping based on the First Vertical Derivative and Tilt Derivative maps.
• Regional geophysical analysis based on the compiled and levelled aeromagnetic data.

Strengths

• Includes four specific magnetic derivative products per map sheet: Residual Total Magnetic Field, RTP, RTP_VD, and RTP_TDR.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
• Colour ramps and legends are provided for each map, aiding interpretation.

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 NTS 105O map sheet area.
