Here's the 5th video in my tree measurement video series. I wanted to lay some groundwork in the previous videos before presenting the sine method, and it was nice to finally pull out a laser and set the tape measure aside.
I think the next video will also be the sine method, but with the eye level below the base. I want to emphasize when the vertical distance to the base gets subtracted from the vertical distance to the top, instead of added. I'm also simultaneously working on "Video Notes" for each video that will have diagrams, formulas, and key takeaways from the videos.
It's viewed best directly on Youtube with the setting changed to HD: https://www.youtube.com/watch?v=vtuO_erqwgQ
I would typically embed the video here, but the youtube BBCode doesn't seem to be working for this particular post.
