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

Reprocessed aeromagnetic data for Yukon map sheet NTS 105I, compiled between November 2016 and March 2017. The Government of Yukon produced four derivative magnetic maps: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and its first 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 interpretation based on Reduced-to-Pole magnetic field maps.
• Regional geophysical analysis using the provided first vertical derivative maps.
• Integrating processed magnetic data with other geospatial layers for mapping.

Strengths

• Data was reprocessed and levelled for consistency across map sheets.
• Four distinct magnetic derivative products are provided for analysis.
• 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 map sheet.
