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.
