Yukon Aeromagnetic Data Reprocessing for NTS 115H, 2016-2017

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 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.
• Mineral exploration targeting based on the Reduced-to-Pole Magnetic Field (RTP) maps.
• Structural analysis based on the First Vertical Derivative of the Reduced-to-Pole Magnetic Field (RTP_VD) maps.
• Edge detection of magnetic sources based on the Tilt Derivative of the Reduced-to-Pole Magnetic Field (RTP_TDR) maps.

Strengths

• Data reprocessing was performed over a defined period from November 2016 to March 2017.
• Includes four specific magnetic derivative map products for each 250k-scale map sheet.
• Data is provided in multiple standard geospatial formats: PDF, GeoTIFF, and Geosoft grid files.

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 115H map sheet area.
