Yukon Aeromagnetic Survey Maps: Reprocessed Magnetic Field Derivatives

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

Use Cases

• Mineral exploration targeting based on magnetic anomaly maps.
• Geological structure interpretation based on Reduced-to-Pole (RTP) magnetic field data.
• Subsurface feature analysis using First Vertical Derivative (RTP_VD) maps.
• Edge detection of magnetic sources using Tilt Derivative (RTP_TDR) maps.
• Regional geological mapping and integration with other geospatial datasets.

Strengths

• Data processing was performed over a defined period from November 2016 to March 2017.
• Four specific magnetic derivative products are generated for each map sheet: Residual Total Magnetic Field, RTP, RTP_VD, and RTP_TDR.
• Maps are provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
• Colour ramps and legends are provided for each map to aid interpretation.

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 Yukon region.
