Yukon Aeromagnetic Survey Maps for NTS 115F, 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/tilt derivative maps provided as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns described in the derivative maps.
• Geological mapping and structural interpretation based on the Reduced-to-Pole Magnetic Field (RTP) data.
• Geophysical modeling and subsurface analysis using the First Vertical Derivative (RTP_VD) and Tilt Derivative (RTP_TDR) maps.

Strengths

• Data processing occurred over a defined 5-month 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.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
• Data may reflect geographic bias inherent to the specific NTS 115F map sheet area in Yukon.
