Yukon Aeromagnetic Survey Reprocessed Derivatives for NTS 106L

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

Use Cases

• Analyze subsurface geological structures based on the Residual Total Magnetic Field maps.
• Interpret magnetic anomalies for mineral exploration using the Reduced-to-Pole Magnetic Field (RTP) maps.
• Enhance edge detection of geological features based on the First Vertical Derivative of the RTP (RTP_VD) maps.
• Map subtle magnetic gradients for geological interpretation using the Tilt Derivative of the RTP (RTP_TDR) maps.

Strengths

• Data was reprocessed and levelled across map sheets between November 2016 and March 2017.
• Four distinct magnetic derivative products are provided for each 250k-scale map.
• Maps are delivered 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.
