Why PyGMT?
A beautiful map is worth a thousand words. To truly understand how powerful PyGMT is, play with it online on Binder! For a quicker introduction, check out our 3 minute overview!
Afterwards, feel free to look at our Tutorials, visit the Gallery, and check out some external PyGMT examples!
About
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 across the Earth, Ocean, and Planetary sciences and beyond.
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 PyData ecosystem:
numpy.ndarrayorpandas.DataFramefor data tables,xarray.DataArrayfor grids andgeopandas.GeoDataFramefor geographical data.
Quickstart
Installation
Simple installation using mamba:
mamba install --channel conda-forge pygmt
If you use conda:
conda install --channel conda-forge pygmt
For other ways to install pygmt, see full installation instructions.
Getting started
As a starting point, you can open a Python interpreter or a Jupyter notebook, and try the following example:
import pygmt
fig = pygmt.Figure()
fig.coast(projection="H10c", region="g", frame=True, land="gray")
fig.show()
For more examples, please have a look at the Gallery and Tutorials.

Contributing Guidelines
Please read our Contributing Guide to see how you can help and give feedback.
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. Equally 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.
