Yukon Magnetic Survey Reprocessed Derivative Maps for NTS 105P

Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. Aeromagnetic data were compiled, merged, and levelled to produce four derivative maps per 250k-scale map sheet. The Government of Yukon provides these maps as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns from the Residual Total Magnetic Field maps.
• Geological structure interpretation based on the Reduced-to-Pole Magnetic Field (RTP) maps.
• Enhancing subtle magnetic features for analysis using the First Vertical Derivative of the RTP maps.
• Edge detection of geological bodies using the Tilt Derivative of the RTP maps.

Strengths

• Reprocessing produced four distinct magnetic derivative maps per map sheet.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
• Colour ramps and legends are included for each map to aid interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific NTS 105P map sheet area.
