Aeromagnetic Survey

Aeromagnetic Survey

An aeromagnetic survey is a common type regarding geophysical survey completed using a magnetometer towed guiding an aircraft. The principle is similar to a magnetic survey completed with a hand-held magnetometer, but allows much bigger areas of the Earth’s surface to become covered quickly regarding regional reconnaissance. The aircraft typically flies in the grid-like pattern using height and brand spacing determining the resolution of the data.
