🚨 This package is still undergoing rapid development. 🚨

All of the API (functions/classes/interfaces) is subject to change until we reach v1.0.0 as per the semantic versioning specification. There may be non-backward compatible changes as we experiment with new design ideas and implement new features. This is not a finished product, use with caution

We welcome any feedback and ideas! Let us know by submitting issues on Github or by posting on our Discourse forum.


PyGMT is a library for processing geospatial and geophysical data and making publication quality maps and figures. It provides a Pythonic interface for the Generic Mapping Tools (GMT), a command-line program widely used in the Earth Sciences.

We rely heavily on new features that have been implemented in GMT 6.0. In particular, a new modern execution mode that greatly simplifies figure creation. These features are not available in the 5.4 version of GMT.

Project goals

  • Make GMT more accessible to new users.

  • Build a Pythonic API for GMT.

  • Interface with the GMT C API directly using ctypes (no system calls).

  • Support for rich display in the Jupyter notebook.

  • Integration with the Scipy stack: numpy.ndarray or pandas.DataFrame for data tables and xarray.DataArray for grids.

Contributing Guidelines

Imposter syndrome disclaimer

We want your help. No, really.

There may be a little voice inside your head that is telling you that you’re not ready to be an open source contributor; that your skills aren’t nearly good enough to contribute. What could you possibly offer?

We assure you that the little voice in your head is wrong.

Being a contributor doesn’t just mean writing code. Equality important contributions include: writing or proof-reading documentation, suggesting or implementing tests, or even giving feedback about the project (including giving feedback about the contribution process). If you’re coming to the project with fresh eyes, you might see the errors and assumptions that seasoned contributors have glossed over. If you can write any code at all, you can contribute code to open source. We are constantly trying out new skills, making mistakes, and learning from those mistakes. That’s how we all improve and we are happy to help others learn.

This disclaimer was adapted from the MetPy project.
