The Magnetic Vertical Gradient: A Study To Quantify Filter Parameters

With the advent of the Image Processor, large regional magnetic data sets are now routinely being processed. Linear and non-linear transformations are commonly applied to the data in order to enhance various aspects of the image. The magnetic vertical gradient is one such transformation. Although employed for many decades on potential field data, it bas in general been used in a qualitative sense. For example, in the form of a high-pass filter. The vertical gradient is not necessarily restricted to qualitative applications, many automated depth estimation techniques make use of the vertical gradient.
