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.
You can even change the code and explore your modified script(s).
Requirements
You need to have a working jupyter installation:
pip2 install jupyter
How to run GRASS GIS from Jupyter notebook
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=`grass74 --config path` # or define path to binaries like /usr/local/grass-7.4.svn
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
