A Jupyter Notebook is a web application that allows you to create and share documents that contain scripts and code, equations, visualizations and explanatory text, combined.

List of selected GRASS GIS Jupyter notebooks

(please expand!)

Intro notebooks:

Collections:

Image processing/OBIA:

PyGRASS and Python:

R and GRASS GIS:

Wildfire Modeling:

Running a Jupyter notebook locally

You can even change the code and explore your modified script(s).

Requirements

You need to have a working Jupyter installation:

pip install jupyter

How to run GRASS GIS from Jupyter notebook

(this section needs to be updated)

Running GRASS from Jupyter notebook requires that Jupyter notebook is installed on your system, and that you set up the environment variables for using GRASS.

For example you can create a script called grass_jupyter.sh that contains the following lines:

# directory where GRASS GIS lives
export GISBASE=`grass78 --config path`   # or define path to binaries like /usr/local/grass-7.8.dev
echo $GISBASE

# generate GISRC
# Defines the system wide value while in a GRASS session
MYGISDBASE=$HOME/grassdata # Change this path to reflect your own 
MYLOC=MyLoc # Change this location name to reflect your own 
MYMAPSET=PERMANENT

# Set the global grassrc file to individual file name
MYGISRC="$HOME/.grassrc.$$"

echo "GISDBASE: $MYGISDBASE" > "$MYGISRC"
echo "LOCATION_NAME: $MYLOC" >> "$MYGISRC"
echo "MAPSET: $MYMAPSET" >> "$MYGISRC"
echo "GRASS_GUI: text" >> "$MYGISRC"

# path to GRASS settings file
export GISRC=$MYGISRC

export LD_LIBRARY_PATH=$GISBASE/lib:$LD_LIBRARY_PATH
export PYTHONPATH=$GISBASE/etc/python:$PYTHONPATH
export PATH=$GISBASE/bin:$GISBASE/scripts:$PATH

# start the notebook in the notebook folder
cd $HOME/notebooks # change to notebooks folder (example; update to your path)

nohup jupyter notebook --ip=0.0.0.0 --port=8888 --debug &

To easily use this script, add this line to your $HOME/.bashrc file:

# update path to script accordingly
alias grass_notebook='sh $HOME/grass_jupyter.sh'

From terminal, in your home directory:

source .bashrc

Now you can start easily your notebook typing in the terminal:

grass_notebook
