Yukon Aeromagnetic Survey Reprocessing for NTS 115P, 2016-2017

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 sheet. The Government of Yukon provides these maps as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Geological interpretation based on the Residual Total Magnetic Field maps.
• Mineral exploration targeting using the Reduced-to-Pole Magnetic Field (RTP) data.
• Edge detection of subsurface features based on the First Vertical Derivative of the RTP.
• Structural analysis using the Tilt Derivative of the Reduced-to-Pole Magnetic Field (RTP_TDR).

Strengths

• Includes four processed magnetic derivative products per map sheet.
• Data is provided in three standard geospatial 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 and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific NTS 115P map sheet area.
