Yukon Aeromagnetic Survey Maps for NTS 105H, 2016-2017 Reprocessing

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 includes four magnetic derivative maps per sheet, 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 structure mapping based on Reduced-to-Pole (RTP) and Tilt Derivative (RTP_TDR) maps.
• Regional geophysical analysis based on the compiled and levelled aeromagnetic data.

Strengths

• Data processing occurred over a defined period from November 2016 to March 2017.
• Four specific magnetic derivative products are generated for each map sheet.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for ML applications.
