Aeromagnetic Survey of the Nisling River Area, Yukon, 2011

37,999 line kilometres of high-resolution magnetic data were collected by Goldak Airborne Surveys for the Geological Survey of Canada between January 25th and March 26th, 2011. The survey used cesium vapour magnetometers and GPS systems, with traverse lines flown at 400 m spacing and a nominal terrain clearance of 100 m. Data were recorded digitally in GEDAS binary format and are available in PDF and ZIP files.

Use Cases

• Map subsurface geological structures based on the high-resolution magnetic field data.
• Identify potential mineral deposits by analyzing magnetic anomalies mentioned in the survey description.
• Integrate with other geophysical datasets for regional geological modeling based on the specified survey area and methods.

Strengths

• 37,999 line kilometres of data provide substantial spatial coverage.
• High sensitivity equipment including three cesium vapour magnetometers was used.
• Survey parameters are precisely documented, including 400 m line spacing and 100 m terrain clearance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal/source bias inherent to open_canada.
