I work in the forestry sector. I signed up for this course because I felt limited by studying only with QGIS textbooks, and it has been incredibly helpful. The last four practical exercises were challenging, but it was useful to see how various functions are combined and applied. It would be great if you could create a separate course in the future consisting entirely of these types of practical, hands-on problems. Since there is no time limit, I plan to rewatch the lessons frequently until I fully master them. Thank you so much for all the hard work you put into preparing this course!!
