This repo holds the Jupyter notebook that will be used for the GRASS for Remote sensing workshop at FOSS4G 2022 in Florence.
We will present and exemplify a subset of GRASS GIS toolsets for satellite imagery data processing and analysis in combination with other core modules and add-ons in a workflow going from data download to supervised classification of different scenes and visualization of results.
We will start with some basic GRASS concepts, but we'll assume Python and remote sensing basic knowledge. Furthermore, participants should install the needed software and download the data in advance.
Clone this repository with git clone
first or download the *.ipynb
file.
Then locally start the Jupyter notebook server from the command line in the
directory containing the *.ipynb
file with:
jupyter notebook
This will open a new browser tab or window with a list of the contents of the current
working directory. Clicking on the *.ipynb
file will start the notebook.
See also the official documentation for The Jupyter Notebook.
We will use GRASS GIS 8.2+. It can be installed either through standalone installers/binaries or through OSGeo-Live (a Linux based virtual machine which includes all OSGeo software and packages).
There are two different options:
For Windows users, we strongly recommend installing GRASS GIS through the OSGeo4W package (first option), since it allows to install all OSGeo software.
Install GRASS GIS 8.2 from the "unstable" package repository:
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install grass grass-gui grass-dev
For other Linux distributions including Fedora and openSuSe, simply install GRASS GIS with the respective package manager. See also here
