Abstract Mirone is a Windows MATLAB-based framework tool developed by the author that allows the display and manipulation of a large number of grid formats through its interface with the Geospatial Data Abstraction Library (GDAL). Its main purpose is to provide users with an easy-to-use graphical interface to the more popular programs of the Generic Mapping Tools (GMT) package. In addition it offers a range of tools dedicated to topics in the earth sciences, including tools for multibeam mission planning, elastic deformation studies, tsunami propagation modeling, earth magnetic field computations and magnetic Parker inversions, Euler rotations and poles computations, plate tectonic reconstructions, and seismicity and focal mechanism plotting. The high-quality mapping and cartographic capabilities for which GMT is renowned is guaranteed through Mirone's ability to automatically generate GMT cshell scripts and dos batch files. User-specific requirements that lie outside the current capabilities of Mirone can be met by simple programming to provide the required functionality.
