Assignment part A
For this assignment, we'll use GRASS GIS in Jupyter Notebooks. The notebooks and associated GRASS data is located in on Github:
Download the code and work through assignment 2A part 1 and part 2. Answer the questions in the notebooks and save the completed notebook as an HTML file and ipynb. Then, upload both files to the Moodle submission portal.2.B Open source software and version control
Outline:- open source software development infrastructure
- development management tools
- working with version control systems
- osgeo software ecosystem
