Test that everything works

If you don't have the Powershell open, please open it. Powershell can be found by clicking on the Windows start menu button and start typing Powershell. MacOSX and Linux users should open theur default terminal window.

Also always make sure you have activated your geopython2023 environment.

(base) micromamba activate geopython2023

(geopython2023)

You can test that the installations have worked by running following commands in a Python console. At first start the Python console:

(geopython2023) python

Type "help", "copyright", "credits" or "license" for more information.
>>>

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import shapely
import fiona
import geopandas as gpd
import cartopy
import mapclassify
import rasterio
import rasterstats
try:
    import gdal
except ImportError:
    from osgeo import gdal

If you don't receive any errors, everything should be working!

In order to close the Python interpreter type exit() and press return/enter or press Ctrl+Z to exit.

Under Mac/Linux you might have to press Ctrl+D to exit.

(geopython2023) >>> exit()

Setting up Jupyter Notebook

The Jupyter Notebook server is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and narrative text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more. Jupyter Lab is an extended version that allows to have several notebooks open at the same time. We will be mostly working with Jupyter Lab.

Before we start Python coding we will make our newly created conda Python environment known to the Jupyter notebook system by installing the kernel, basically the execution engine link from Jupyter web notebook to our Python environment:

Make sure you are in your dedicated working directory, your "geopython2023" folder, on the Command line window (Powershell). And make sure the geopython2023 conda environment is activated:

(base) micromamba activate geopython2023

(geopython2023) python -m ipykernel install --user --name geopython2023

That should be it. You should now be able to start the Jupyter notebook server:

(geopython2023) jupyter lab

This should open a webpage in your default webbrowser.

Note

Don't close the console window nor the browser window where the notebooks opened. Always use the "File" -> "Save and Checkpoint" and then -> "Close and Halt" menu options in the notebooks, and the "Quit" button on the main notebook server webpage.
