Yukon Aeromagnetic Survey Maps for NTS 105N, 2016-2017 Reprocessing

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

• Mineral exploration targeting based on magnetic anomaly patterns.
• Geological mapping and structural interpretation using derivative magnetic fields.
• Integrating processed magnetic data with other geophysical or geological datasets for regional analysis.

Strengths

• Data processing involved merging datasets of different resolutions and individual levelling for each map sheet.
• Four specific magnetic derivative maps were produced for each 250k-scale map: Residual Total Magnetic Field, Reduced-to-Pole, First Vertical Derivative, and Tilt Derivative.
• Maps are provided in multiple standard geospatial formats (PDF, GeoTIFF, Geosoft grid) with colour ramps and legends.

Limitations

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