+
+The workshop showcases GRASS tools for satellite imagery processing and analysis,
+covering workflows from data acquisition to supervised classification and visualization. 
+It is all contained in a Jupyter Notebook using GRASS Python interface and can be run
+in Google Colab, so no local software installation is required.

+Special acknowledgements to Markus Neteler and Maris Nartiss who were part of an earlier
+edition of this workshop and also prepared the Sentinel-2 dataset 🙌
