Hi David! Thanks for your comments and you are right. But these videos are part of a lecture series so if the videos are watched in sequence then they make more sense. I also base the videos on what I speak to the students of during class so sometimes they won't make much sense if you have not attended the previous theory lecture. I made the videos public on request of my students. I hope that explains them.
Great video, thanks :) Unsure why this was never covered in my GIS lectures, but it was simple enough to understand from yours!
..I feel like this video starts in the middle of the subject. Is there a predecessor to this video?
