Airborne Radiometric Survey Data From 2005-2006 Tellus Campaign

Geophysical data from the 2005-2006 Tellus Survey collected over 80,458 line kilometers by the British Geological Survey and Finnish GTK. The dataset includes magnetic, electromagnetic, and terrestrial gamma-radiation measurements recorded from airborne platforms with specific flight line spacing and sample intervals.

Use Cases

• Analyze terrestrial gamma-radiation measurements to map natural radioactivity and geological formations.
• Model magnetic field data collected at 7-meter sample intervals for subsurface structural interpretation.
• Integrate electromagnetic survey data acquired at 17.5-meter intervals with magnetic data for mineral exploration targeting.
• Study the variation in survey ground clearance (56m rural, 240m urban) against radiometric signal response.

Strengths

• Extensive spatial coverage from 80,458 line kilometers of airborne survey.
• Multi-parameter geophysical data including magnetic, electromagnetic, and gamma-radiation measurements.
• Precisely documented acquisition parameters: 200m flight line spacing, 56m/240m ground clearances, and defined sample intervals (7m, 17.5m, 70m).

Limitations

• Data is from a single campaign in 2005-2006 and may not reflect current conditions.
• Unknown sample count (rows) and specific column structure for direct machine learning application.
• Primary format is HTML, which may require significant parsing and conversion for analytical use.
