Geophysical Surveys

Include geophysical coverage maps (High and low resolution)

Low resolution

  • Countrywide low resolution airborne geophysical surveys were conducted by Geosurvey International (GmbH) in 1977 to 1979.
  • High-altitude (200 m) and 1 km line spacing airborne geophysical mapping.
  • Data is available in QDS-wise as raw and/or processed. Includes magnetic and radiometric data..

High resolution
Systematic high resolution airborne geophysical survey has been conducted in selected areas by mineral exploration companies and other agencies such as BGR, UNDP and Geological Survey of Finland (GTK).

The new high resolution airborne geophysical data has been acquired by GTK in 2003, at 200m line spacing and 45 m flight altitude

Measured geophysical parameters:

  • Electromagnetic field with two or four frequencies
  • Induced Polarization
  • Magnetic total field
  • Spectrometer
  • Earth’s gamma radiation (K, U, Th and total radio
