Reprocessing of Yukon magnetic data was performed between November 2016 and March 2017. Aeromagnetic data were compiled and merged to produce four derivative maps per 250k-scale map sheet. These maps are provided as PDFs, GeoTIFFs, and Geosoft grid files by the Government of Yukon.
Use Cases
- Identify geological structures based on Residual Total Magnetic Field maps
- Analyze subsurface magnetic anomalies using Reduced-to-Pole Magnetic Field (RTP) maps
- Enhance edge detection of magnetic sources using the First Vertical Derivative of the RTP
- Interpret magnetic data with reduced noise using the Tilt Derivative of the RTP
Strengths
- Data reprocessing was performed over a defined 5-month period (Nov 2016 - Mar 2017)
- Four distinct magnetic derivative maps are produced for each 250k-scale map sheet
- Data is provided 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 total data size are unknown, which may limit suitability assessment
