Yukon Aeromagnetic Survey Reprocessing with Four Derivative Maps

Reprocessing of magnetic data for Yukon was performed between November 2016 and March 2017. Aeromagnetic data were compiled and merged to produce a series of levelled images for each 250k-scale map sheet. The dataset includes four magnetic derivative maps provided as PDFs, GeoTIFFs, and Geosoft grid files by the Government of Yukon.

Use Cases

• Mineral exploration targeting based on processed magnetic field derivatives.
• Geological mapping and structural interpretation based on Reduced-to-Pole and Tilt Derivative maps.
• Integrating magnetic data with other geophysical surveys using the provided Geosoft grid files.

Strengths

• Includes four specific processed magnetic derivative products: Residual Total Magnetic Field, Reduced-to-Pole, First Vertical Derivative, and Tilt Derivative.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
• Reprocessing 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.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific NTS 105K map sheet area.
