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

Reprocessed aeromagnetic survey data for the Yukon's NTS 105L map sheet area. The data was compiled and merged from different resolutions between November 2016 and March 2017, producing four derivative magnetic field maps per 250k-scale sheet. The Government of Yukon provides these maps as PDFs, GeoTIFFs, and Geosoft grid files.

Use Cases

• Geological mapping based on the processed magnetic field derivatives.
• Mineral exploration targeting using the Reduced-to-Pole (RTP) and Tilt Derivative (RTP_TDR) maps.
• Subsurface structure analysis based on the First Vertical Derivative (RTP_VD) data.

Strengths

• Data was reprocessed and levelled for consistency across map sheets.
• Four specific derivative products (Residual TMF, RTP, RTP_VD, RTP_TDR) are provided for each map.
• Maps are available in three standard geospatial formats (PDF, GeoTIFF, Geosoft grid).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
