MEGATEM II Airborne Geophysical Survey, Central Stevenson Ridge, Yukon

MEGATEM® II airborne electromagnetic data was collected over the central Stevenson Ridge area in Yukon, Canada. The survey was flown with a flight line spacing of 400 meters on a 90-270 degree orientation and a nominal terrain clearance of 60 meters for the EM receiver bird. This dataset is provided by the Government of Yukon and was last updated in May 2026.

Use Cases

• Map subsurface conductivity anomalies based on the airborne electromagnetic (EM) data.
• Identify potential mineral deposits using the geophysical signatures from the survey.
• Integrate survey data with geological maps for regional structural analysis.
• Model the depth to bedrock or overburden thickness using the EM response collected at 60m clearance.

Strengths

• Survey parameters are explicitly stated, including a 400m flight line spacing and 60m nominal terrain clearance.
• Data originates from the authoritative Government of Yukon and is licensed for open use (OGL-CA-2.0).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
