Reprocessing of Yukon Magnetic Data for NTS 117D

Yukon aeromagnetic data was reprocessed between November 2016 and March 2017. The data were compiled, merged from different resolutions, and levelled to produce derivative maps for each 250k-scale map sheet. The derivative maps include Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and its first vertical and tilt derivatives.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns.
• Geological mapping and structural interpretation using derivative magnetic fields.
• Integrating processed magnetic data with other geophysical or geological datasets for regional studies.

Strengths

• Data processing was performed over a defined period from November 2016 to March 2017.
• Four specific magnetic derivative maps were produced for each map sheet: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, RTP_VD, and RTP_TDR.
• Maps are provided in multiple standard geospatial formats: PDFs, GeoTIFFs, and Geosoft grid files.

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.
