Yukon Aeromagnetic Survey Reprocessed Derivative Maps for NTS 116O

Reprocessed aeromagnetic data for Yukon map sheet NTS 116O. The Government of Yukon compiled and merged data of different resolutions between November 2016 and March 2017, producing four magnetic derivative maps per 250k-scale sheet. The processed maps are provided as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns from the derivative maps.
• Geological mapping and structural interpretation using the Reduced-to-Pole and tilt derivative data.
• Integrating processed magnetic data with other geophysical or geological datasets for regional analysis.

Strengths

• Provides four specific derivative map products per map sheet: Residual Total Magnetic Field, Reduced-to-Pole, First Vertical Derivative, and Tilt Derivative.
• Data is available in three standard geospatial formats: PDFs, GeoTIFFs, and Geosoft grid files.
• Includes colour ramps and legends for each map to aid interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description lacks specifics on the spatial resolution, flight line spacing, or total area covered.
• Row count is unknown, which may limit suitability assessment for large-scale ML projects.
