Reprocessed aeromagnetic data for Yukon's NTS 105J map sheet includes four derivative maps. The data was compiled and levelled between November 2016 and March 2017 by the Government of Yukon. Maps are provided 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.
- Geophysical data integration for regional geological studies.
Strengths
- Includes four processed magnetic derivative maps: Residual Total Magnetic Field, Reduced-to-Pole Magnetic Field, and its first vertical and tilt derivatives.
- Data is provided in multiple standard geospatial formats (PDF, GeoTIFF, Geosoft grid) with colour ramps and legends.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
