Dam! I need a DUMB video to understand how to do the things properly, in the field and in the office. I've just relized I know NOTHING. That's hurting a lot. Thanks for this awesome video.
Awesome! The conclusion in the end is spot on. Please show how to adjust networks!
Absolutely, it will be a topic in upcoming videos!!
After this video, it is my favorite channel.
Thank you for doing such content.
Looking forward to more videos on control. I’m blown away that the control I receive most of the time as a contractor is set using gnss only. We are building large concrete structures and even high rise buildings and this is the first I have heard mention of a least squares adjustment like this. In the past, guys have measured traverses through provided control to tighten it up but this seems like a much better way to ensure reliable setups through the course of the job. I went to a site today that has lost all of its original ground control and they are on level 6 of 17. It’s a disaster as all of the control they are using now has been set with crappy resections.
I wish I could say that kind of situation you’re having to deal with is rare but I’m sure in your own experience you know it isn’t. Control networks being set up without a least squares adjustment is never a good idea.
Your channel is a super find! Would you be able to share the dataset, in order to use this as an exercise?
Yea I can do that. Send me a message on LinkedIn (Shea Gleadle) and I'll forward it to you.
great video :)
I just like the name Crandall lol
Haha, named after Charles Lee Crandall who developed his method of adjustment in 1901.
