PyGMT: Pythonic Generic Mapping Tools
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.
# install pygmt environment conda config --prepend channels conda-forge conda create --name pygmt python=3.8 pip numpy pandas xarray netcdf4 packaging gmt # open pygmt environment conda activate pygmt # install pygmt conda install pygmt # test conda install pytest pytest-mpl ipython import pygmt pygmt.show_versions() pygmt.test()
2. Finding the GMT shared library
Sometimes, PyGMT will be unable to find the correct version of the GMT shared library. This can happen if you have multiple versions of GMT installed.
You can tell PyGMT exactly where to look for libgmt by setting the GMT_LIBRARY_PATH environment variable. This should be set to the directory where libgmt.so, libgmt.dylib or gmt.dll can be found for Linux, macOS and Windows respectively. e.g. in a terminal run:
# Linux/macOS export GMT_LIBRARY_PATH=$HOME/anaconda3/envs/pygmt/lib # Windows set "GMT_LIBRARY_PATH=C:\Users\USERNAME\Anaconda3\envs\pygmt\Library\bin\"
