GRAV-MAG SUITE is a MATLAB-based program that has been developed for processing potential field data. The program is composed by several tools, which involve miscellaneous field transformations and enhancing filters, semiquantitative methods, and simple shape forward modeling algorithms. GRAV-MAG SUITE provides a graphical user interface (GUI) that facilitates the user's interaction with the program. In order to illustrate the program functionalities, a set of tools will be applied on a synthetic data composed by six prisms representing the most typical geological structures.
