Yukon Aeromagnetic Survey Maps: Reprocessed Magnetic Derivatives for NTS 116N

Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. Aeromagnetic data were compiled and merged to produce a series of levelled derivative maps for each 250k-scale map sheet. The dataset is provided by the Government of Yukon and includes maps in PDF, GeoTIFF, and Geosoft grid formats.

Use Cases

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

Strengths

• Includes four specific magnetic derivative map types for each 250k-scale map sheet.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid files.
• Colour ramps and legends are provided 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 116N map sheet area.
