Yukon Aeromagnetic Data Reprocessing for NTS 115J

Yukon aeromagnetic data was reprocessed between November 2016 and March 2017. The work involved compiling and merging data of different resolutions to produce a series of levelled derivative maps for each 250k-scale map sheet. The maps are provided as PDFs, GeoTIFFs, and Geosoft grid files by the Government of Yukon.

Use Cases

• Mineral exploration targeting based on magnetic derivative maps like Reduced-to-Pole (RTP).
• Geological structure interpretation based on the First Vertical Derivative of the RTP field.
• Regional geological mapping using the Residual Total Magnetic Field data.
• Geophysical anomaly analysis using the Tilt Derivative of the RTP field.

Strengths

• Data was reprocessed and levelled across map sheets between 2016 and 2017.
• Four distinct magnetic derivative maps are produced for each 250k-scale 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 and dataset size are unknown, which may limit suitability assessment.
