Magnetic methods measure the earth’s magnetic field and anomalies caused by naturally occurring and manmade ferrous materials. Theoretical models can be used to approximate size, depth, shape, and composition of various targets. Collier utilizes magnetic methods on a variety of engineering and environmental applications including drone-based magnetometer systems.
