Yukon Aeromagnetic Data Reprocessing for NTS 105G, 2016-2017

Yukon, Canada, is the geographic scope for this reprocessed aeromagnetic dataset. The data was compiled and merged from different resolutions between November 2016 and March 2017, producing a series of levelled magnetic derivative maps. The Government of Yukon provides these maps as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral exploration targeting based on magnetic anomaly maps.
• Geological structure mapping based on the Reduced-to-Pole (RTP) magnetic field.
• Subsurface feature enhancement based on the First Vertical Derivative (RTP_VD) and Tilt Derivative (RTP_TDR) maps.
• Integrating magnetic data with other geospatial layers for regional analysis.

Strengths

• Includes four processed magnetic derivative maps (Residual Total Magnetic Field, RTP, RTP_VD, RTP_TDR) for each 250k-scale map sheet.
• Data is provided in three standard geospatial formats: PDF, GeoTIFF, and Geosoft grid.
• 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 for large-scale ML tasks.
• Data may reflect geographic bias inherent to the specific NTS 105G map sheet area.
