Yukon Magnetic Survey Reprocessing for NTS 095D, 2016-2017

Reprocessed aeromagnetic data for Yukon, Canada, compiled and merged from different resolutions between November 2016 and March 2017. The dataset includes four derivative magnetic field maps per 250k-scale map sheet, produced by the Government of Yukon. Maps are provided as PDFs, GeoTIFFs, and Geosoft grid files with accompanying colour ramps.

Use Cases

• Geological interpretation based on the Residual Total Magnetic Field maps.
• Mineral exploration targeting using the Reduced-to-Pole Magnetic Field (RTP) maps.
• Edge detection of magnetic sources based on the First Vertical Derivative of the RTP maps.
• Enhancing subtle magnetic features using the Tilt Derivative of the RTP maps.

Strengths

• Data was reprocessed and levelled for consistency across map sheets.
• Provides four distinct magnetic derivative products per map sheet.
• Offers data in three common geospatial formats (PDF, GeoTIFF, Geosoft grid).

Limitations

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