Collection of Python scripts or Jupyter notebooks (supported by JupyterLab) to reproduce some of the geographic and geophysical maps shown in the publications I am involved in. To prepare these maps, PyGMT the Python wrapper for the Generic Mapping Tools (GMT) is used.
Please note: Scripts or notebooks are available up on acceptance of the related publication.
Please note: Besides PyGMT and GMT, the tools Jupyter, NumPy, pandas, ObsPy, pymagglobal, GeoPandas and geodatasets are used. The required versions are given in the single folders as well as notebooks or scripts.
If you make use of this material, please acknowledge the relating publications in which framework these scripts and notebooks were written:
