Reprocessing of magnetic data for Yukon was performed between November 2016 and March 2017. Aeromagnetic data were compiled, merged, and levelled to produce derivative maps for each 250k-scale map sheet. 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 based on processed magnetic fields.
- Integrating magnetic data into regional geophysical models based on the provided grid files.
Strengths
- Data was reprocessed and levelled across map sheets between 2016 and 2017.
- Four derivative magnetic maps are produced per sheet: Residual Total Magnetic Field, Reduced-to-Pole, and its first vertical and tilt derivatives.
- Data is provided in three standard 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.
