Download and install of QGIS
Download and install anaconda
conda environment creation
installation of libraries according to
https://github.com/rolfbecker/EE_3.07_Geodata_WS2022/tree/main/gdms0020_Course_Preparation
Correction of packages: jupyterlab pandas geopandas shapely fiona pyproj rasterio sqlalchemy psycopg2 ipython-sql bs4
https://cs231n.github.io/python-numpy-tutorial/ up to numpy

Extra material:

* Finished the numpy tutorial from cs231. Skipped the image processing for now
* Followed partially the hands-on-ml3 tutorial (tools_pandas.ipynb). Material covered:
* import pandas and alias
* Series: create from list, give index, give name, create from dictionary. slicing, alignment, plotting
* Handle time with pd.date_range()
* Creating a Dataframe: by dictionary.
* selecting columns, accesing values, filtering, transposing. skipped multi-indexing, stacking and unstacking,
* datafream read: read_csv and read_excel. And dat frame write

To correct:

1) Explain what the grabfile function is doing with doc string
2) Show them what the problem of the file is by uploading in QGIS
3) Let them import the file by themselves, So they see the problem again
4) Notice that station ID is being read as integer. So correct that by a dtype dictionary
5) Update the administrative boundaries links

To correct:

Give the LL and UR coordinates and let the. figure out the rest
Show an example of usage for Point and for Line in shapely. Ask then for creating the polygon
geopandas as a tool to have data frames with georeferenced data. So let them use the example and modify the data as they need it
Show how to find the correct item in the documentation
Let them practice by repeating the steps with a different bounding box or with a different shape
