Yukon Magnetic Survey Reprocessing: Four Derivative Maps per 250k Sheet

Reprocessing of Yukon aeromagnetic data was performed between November 2016 and March 2017. The Government of Yukon compiled and merged data of different resolutions to produce individually levelled images for each map sheet. For each 250k-scale map, four magnetic derivative maps were generated: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and its first vertical and tilt derivatives.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns
• Geological structure mapping using the tilt derivative (RTP_TDR) maps
• Regional geophysical analysis using the Reduced-to-Pole (RTP) magnetic field data
• Integrating magnetic data with other geoscience datasets for the NTS 116O area

Strengths

• Four distinct processed magnetic derivative products per map sheet
• Data provided in three standard geospatial formats (PDF, GeoTIFF, Geosoft grid)
• Processing period is explicitly stated as November 2016 to March 2017
• Colour ramps and legends are included for each map

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the specific NTS 116O map sheet area
