A toolbox for Earth, Ocean, and Planetary Science

GMT is widely used across the Earth, Ocean, and Planetary sciences. A diverse community use GMT to process data, generate publication-quality illustrations, automate workflows, and make animations. Scientific journals, posters at meetings, and Wikipedia pages display illustrations made by GMT.

Publication quality figures and animations

Whether Cartesian, geographic, or time-series, GMT can process your data. GMT enables you to explore new ways to analyze data and to build custom displays for drafts, publications, or final presentations. GMT allows unlimited customization via scripting in several languages.

C, MATLAB, Julia, Python

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++.
