Visualization of Magnetometer Data

Abstract

The aim of processing and subsequent visualization of magnetometer data is to provide both the specialist and non‐specialist with a dataset that can inform decision‐making and subsequent risk management in a sensible and appropriate way. Magnetometer data are complex, and require careful processing and thoughtful visualization to transform them from a stream of measured values into a clear, interpretable dataset. Key generic processing routines are introduced which deal with noise reduction and enhancement of magnetic anomalies, to improve the visual appearance and positioning of data. Common visualization approaches of processed data are also highlighted.
