Description
Between January 25th and March 26th, 2011, Goldak Airborne Surveys collected 37,999 line kilometres of high-resolution magnetic data for the Geological Survey of Canada. The survey covered the Nisling River area in Yukon, using cesium vapour magnetometers and differential GPS. Traverse lines were flown at a 400 m spacing with a nominal terrain clearance of 100 m.
Use Cases
Map regional geological structures based on magnetic field anomalies.
Assess mineral exploration potential based on high-resolution magnetic data.
Conduct geophysical research based on a large, systematically collected aeromagnetic dataset.
Strengths
37,999 line kilometres of high-resolution magnetic data were collected.
Survey used high-sensitivity cesium vapour magnetometers and differential GPS for positioning.
Traverse lines were flown at a consistent 400 m spacing with 100 m nominal terrain clearance.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
