Yukon Aeromagnetic Survey Maps for NTS 116A

Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. The Government of Yukon compiled aeromagnetic data, merged different resolutions, and produced individually levelled images for each map sheet. For each 250k-scale map, four derivative maps were produced: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, its First Vertical Derivative, and its Tilt Derivative.

Use Cases

• Map subsurface geological structures based on the processed magnetic field data.
• Identify potential mineral deposits based on anomalies in the Reduced-to-Pole Magnetic Field.
• Enhance geological interpretation using the First Vertical Derivative and Tilt Derivative maps.
• Integrate magnetic data with other geospatial layers for regional geological analysis.

Strengths

• Data was reprocessed and levelled for consistency across map sheets.
• Four distinct magnetic derivative maps are provided for each 250k-scale map.
• Data is available in multiple 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.
• Data may reflect geographic bias inherent to the specific NTS 116A map sheet area.
