The invention concerns a method for acquiring and processing magnetometric data for representing on an at least two-dimensional map magnetometric characteristics of a geographical zone including a step of measuring the intensity of a magnetic field () on a geographical zone producing a set of magnetometric data of intensity B(s), a step of computing 2D interpolation (), a step of computing reduction at the poles () and a step of computing an analytical signal (). The invention is characterized in that it includes sectioning the map of magnetic disturbances into a matrix of pixels, a step of locally updating in real time the map of magnetic anomalies, a step of locally updating in real time the map of 2D interpolation by applying the 2D interpolation calculation in the neighborhood of the updated pixel, a step of locally updating in real time the 2D map of reduction at the poles and a step of locally updating in real time the 2D map of the analytical signal.
