AS Assignment

  • Do the exercises in this unit.
  • Extract the AlphaEarth embeddings for all plots and save them as plot_embeddings_<year>.csv. Commit your GEE script (copy it into a .js file) and your R script to your GitHub classroom repository.
  • Include the PCA plot from the exercise in an R Markdown (html) document.
  • Write a short reflection (200–300 words) in the same document:
    • How could embeddings help in your own research project?
    • Where could they mislead you? Think about interpretability, bias, and the spatial scale of your plots.
    • Would you use embeddings, classic predictors, or both? Why?

  • Read the Overview of Unit 07 to prepare for setting up your research project.

  • For further reading (not part of this course), look at the TESSERA paper and try the geotessera Python package.
