GravPack: a MATLAB-based gravity data processing package

Abstract

GravPack is a gravity data processing package developed utilizing MATLAB. The package is aimed at providing a standalone and processing environment for Bouguer gravity data by putting various modules (such as spectral analysis, filtering, boundary analyses, and modelling) together. It is designed to be user-friendly, which results in an easy-to-use graphical user interface (GUI) consisting of a single window with separate tabs for each processing step. Aside from Bouguer gravity data processing, GravPack includes other useful features such as coordinate conversion, cropping, gridding, re-formatting data files, and displaying data in various ways, all of which can be used on various datasets other than gravity data. In this paper, the theoretical background for gravity data processing and interpretation is summarized. Then, GravPack and its capability of applying these processing steps are introduced using Bouguer gravity data of Konya-Cumra area (Western Anatolia). And finally, current capabilities and superiorities of GravPack are discussed.
