Instructor notes

Episode 1

  • The exercise Exercise: Search satellite scenes using metadata filters needs extra attention. Its output search.json is required for the later episodes. Therefore we recommend:
    • Do not skip this exercise;
    • Think twice when you would like to change the query arguments in this exercise;
    • Make sure all the audience have the output search.json before continuing.

Episode 3

  • brpgewaspercelen_definitief_2020_small.gpkg was created because the original file was too large to download and load. Original file, which was ~500Mb could take several minutes to load, and could crash the Jupyter terminal.
  • The cropped version of brpgewaspercelen_definitief_2020_small.gpkg: data/fields_cropped.shp is required for later episodes.
  • The “Modify the geometry of a GeoDataFrame” section is optional and can be skipped without consequences.

Episode 4

  • It is not recommended to plot the visual band directly, due to its size (3 x 10980 x 10980). Please plot the overview as in the teaching material.
  • The clipped raster data: raster_clip.tif is required for later episodes.

Episode 5

  • The calculated NDVI: NDVI.tif is required for later episodes.
  • The calculated classification identifier: NDVI_classified.tif is required for later episodes.

Workshop setup

  • Consider using mamba for speeding up the Python environment setup.
  • Make sure the audience has downloaded the three vector datasets to the data repository.
