The Geological Survey of Norway (NGU) plans to carry out geophysical aerial measurements in the eastern areas of Innlandet County, (previously Hedmark County).

The measurements, which will be carried out in 2020, cover an area of 5 000 km2, or 25 000 line-km, plus tie-lines. Flights must be undertaken at 60 m height over undulating terrain, 200 m line distance in the southernmost areas. We would like measurements to be carried out in the northern area at a later date, then with 400 m line distance.

Competent tenderers are invited to submit a tender for the combined magnetic, electromagnetic, and radiometric measurements, which will be undertaken in summer 2020, with an option for an extension to complete the measurements in the entire area in subsequent years.
