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: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and its first vertical and tilt derivatives. The maps are provided by the Government of Yukon as PDFs, GeoTIFFs, and Geosoft grid files.
Use Cases
- Mineral exploration targeting based on magnetic anomaly patterns.
- Geological mapping and structural interpretation using derivative magnetic fields.
- Integrating processed magnetic data with other geophysical or geological datasets for regional analysis.
Strengths
- Data processing produced four standardized magnetic derivative maps for each map sheet.
- Maps are provided in three common geospatial formats: PDF, GeoTIFF, and Geosoft grid.
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.
