Aerial Magnetic Survey Data From 2005-2006 Tellus Project

2005-2006 airborne geophysical survey collected 80,458 line kilometers of magnetic, electromagnetic, and gamma-radiation data. The Joint Airborne-geoscience Capability (JAC), a venture between the Finnish and British Geological Surveys, conducted the flights with 200-meter line spacing and variable ground clearance.

Use Cases

• Map magnetic anomaly patterns from the 80,458 line km of survey data for geological structure interpretation.
• Analyze electromagnetic and gamma-radiation data correlations across the surveyed flight lines.
• Model subsurface geology using the integrated magnetic and electromagnetic measurements collected at 7m and 17.5m sample intervals.

Strengths

• 80,458 line kilometers of systematically acquired airborne data provides large spatial coverage.
• Data integrates three geophysical methods: magnetics, electromagnetics, and terrestrial gamma-radiation.
• Precise acquisition parameters are documented, including 200m flight line spacing and defined sample intervals.

Limitations

• Data is from a single 2005-2006 campaign and may not reflect current subsurface conditions.
• The HTML file format is not optimal for direct quantitative analysis and may require data extraction.
• Specific row/column counts and data structure are unknown, complicating initial assessment.
