This repo holds the Jupyter notebook that will be used for the GRASS for Earth Observation workshop at FOSS4G 2024 in Belem, Brazil.
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 addons in a workflow going from data search and download to supervised classification of different scenes and visualization of results.
❗ The workshop will be run in Google Colab, attendants do not need to install any software in their machines.
To open the notebook in Google Colab, just use the URL of this repository as shown below:
We will use GRASS GIS 8.4+. It can be installed either through standalone installers/binaries or through OSGeo-Live (a Linux-based virtual machine that 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 the installation of all OSGeo software.
Install GRASS GIS 8.4 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, install GRASS GIS with the respective package manager. See also here.

Please install other required Python packages with the following:
python -m pip install eodag[usgs] notebook folium ipyleaflet scikit-learn pandas numpy seaborn matplotlib
Please download the following files in advance:
- North Carolina (NC) sample data: https://grass.osgeo.org/sampledata/north_carolina/nc_spm_08_grass7.zip
- List of available data in the North Carolina sample dataset.
- Sentinel-2 scenes: https://data.neteler.org/foss4g2022/sentinel.zip
- NC NLCD 2019 map in GRASS GIS format: https://data.neteler.org/foss4g2022/nc_nlcd2019.pack
We'll use Sentinel-2 data and hence users must be registered at the Copernicus Data Space Ecosystem.
