Yukon Aeromagnetic Survey Reprocessing for NTS 106B

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 map sheet. The dataset is provided by the Government of Yukon and includes maps as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Geological interpretation based on the Residual Total Magnetic Field maps.
• Subsurface structure analysis using the Reduced-to-Pole Magnetic Field (RTP) maps.
• Edge detection of magnetic sources based on the First Vertical Derivative of the RTP maps.
• Mapping subtle magnetic features using the Tilt Derivative of the RTP maps.

Strengths

• Includes four processed magnetic derivative maps per map sheet.
• Data was reprocessed and levelled between 2016 and 2017.
• Maps are provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.

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.
