The code snippet in the notebook can be used to convert a WKT representation of the geometries to a grayscale mask image. Note that the script expects the WKT to be formatted with absolute coordinates. Additionally, any invalid geometries should be fixed or removed. You may use the recipes for coordinate conversion and fixing invalid geometries (@TODO:link recipe) for these steps.
No special installation steps required. Follow the virtual environment setup on the main repository page and then follow the steps in the notebook.
