Yukon Aeromagnetic Survey Maps for NTS 105C, 2016-2017

Reprocessed aeromagnetic data for Yukon map sheet NTS 105C, compiled between November 2016 and March 2017. The Government of Yukon produced derivative maps including Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and their vertical and tilt derivatives. Maps are provided as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns.
• Geological structure mapping based on Reduced-to-Pole Magnetic Field data.
• Subsurface feature analysis based on First Vertical Derivative maps.
• Regional geophysical studies based on levelled, merged aeromagnetic data.

Strengths

• Data was reprocessed and levelled specifically for map sheet NTS 105C.
• Four distinct magnetic derivative map types are produced for each 250k-scale map.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
