Yukon Aeromagnetic Survey Maps with Four Derivative Products

Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. Aeromagnetic data were compiled and merged to produce four derivative maps per 250k-scale map sheet: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and its first vertical and tilt derivatives. The maps are provided by the Government of Yukon in PDF, GeoTIFF, and Geosoft grid formats.

Use Cases

• Map subsurface geological structures based on processed magnetic field data.
• Identify potential mineral deposits based on magnetic anomaly patterns.
• Conduct regional geological analysis based on the 250k-scale map sheets.
• Integrate magnetic derivative products into geological modeling software based on the provided Geosoft grid files.

Strengths

• Four distinct magnetic derivative maps produced for each 250k-scale sheet.
• Data provided in three interoperable formats: PDF, GeoTIFF, and Geosoft grid.
• Reprocessing work was conducted over a defined five-month period from November 2016 to March 2017.

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 Yukon region.
