Yukon Aeromagnetic Survey Reprocessing for NTS 115C, 2016-2017

Reprocessed aeromagnetic data for Yukon, Canada, specifically for National Topographic System map sheet 115C. The Government of Yukon compiled and merged data of different resolutions between November 2016 and March 2017, producing a series of levelled derivative maps. The dataset includes four magnetic derivative maps per 250k-scale map sheet, provided as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Mineral exploration targeting based on magnetic anomaly patterns from the Residual Total Magnetic Field and Reduced-to-Pole maps.
• Geological structure interpretation using the First Vertical Derivative and Tilt Derivative maps to highlight edges and contacts.
• Regional geophysical mapping and data integration for the NTS 115C area using the provided Geosoft grids and GeoTIFFs.

Strengths

• Includes four specific processed magnetic derivative products per map sheet: Residual Total Magnetic Field, Reduced-to-Pole, First Vertical Derivative, and Tilt Derivative.
• Data is provided in three standard geospatial formats: PDF for viewing, GeoTIFF for GIS, and Geosoft grid for specialized analysis.
• Reprocessing work was conducted during a defined period from November 2016 to March 2017.

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 statistical analysis.
• The description does not specify the original flight line resolution or the exact area coverage beyond the NTS 115C sheet.
