Yukon Magnetic Survey Reprocessing for NTS 117C, 2016-2017

Reprocessing of magnetic data for Yukon 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 is provided by the Government of Yukon and includes maps in PDF, GeoTIFF, and Geosoft grid formats.

Use Cases

• Geological interpretation based on the Residual Total Magnetic Field maps.
• Mineral prospectivity mapping based on the Reduced-to-Pole Magnetic Field (RTP) data.
• Edge detection for geological structures based on the First Vertical Derivative of the RTP.
• Subsurface feature analysis based on the Tilt Derivative of the RTP.

Strengths

• Includes four processed magnetic derivative maps per 250k-scale map sheet.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
• Reprocessing work was conducted over a defined period from November 2016 to March 2017.

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.
