The content of “Non-Spatial Geodataprocessing” looks great. However, the general criticism would be that the chapter does not really tell a story or outline a real-world use case. So it would probably be good if you start quite early on with an example of basic datasets and what more information one can get out of the dataset with simple calculations.
The technical aspect of the content is great and everything is there. You just need to put it in a “story”.
