A toolbox for Earth, Ocean, and Planetary Science

The Generic Mapping Tools (GMT) are widely used across the Earth, Ocean, and Planetary sciences and beyond. A diverse community uses GMT to process data, generate publication-quality illustrations, automate workflows, and make animations. Scientific journals, posters at meetings, Wikipedia pages, and many more publications display illustrations made by GMT. And the best part: it is free, open source software licensed under the LGPL.

GMT has been used from UNIX and Windows command lines for decades. More recently, GMT has been rebuilt as an Application Programming Interface (API) and can now be accessed via wrapper libraries from MATLAB/Octave, Julia, and Python, as well from custom programs written in C or C++.
