Python for Geoscientists

  • An understanding of the Python programming syntax

  • Importing and exporting common data formats

  • Visualising graph data with matplotlib

  • Mapping geoscientific data with Cartopy

  • Using common Python libraries (e.g. numpy and scipy) to solve simple geospatial problems

Python environment

Our preferred installation Python installation is via conda, which uses separate environment to minimise dependency conflicts

conda install -c conda-forge gplately scikit-learn jupyter

We recommend creating a new conda environment inside which to install these dependencies. This avoids any potential conflicts in your base Python environment. In the example below we create a new environment called "my-env"

conda create -n my-env
conda activate my-env
conda install -c conda-forge gplately scikit-learn jupyter

my-env needs to be activated whenever you use GPlately: i.e. conda activate my-env.

Assessment

Two Jupyter notebooks

Exercise 1

  • Mapping bathymetry and age of ocean floor
  • Image processing (interpolation + smoothing)
  • Curve fitting

Exercise 2

  • Build a map of your field area
  • Plot geospatial data
  • Multi-pane maps

Each of these exercises will build on notebooks that we will cover during the course.

Submission

  • Use your GitHub account to version control your work on the exercises.
    • On your own GitHub account e.g. github.com/username/honours
  • Email me a link to your completed exercises to me by Friday the 24th of May.
