Geodesy and GPS Class

Looking forward to the next installment.

What Mark said.
Thanks,

One comment. Missing is any mention of the existence of local (flat earth) control. Your article might leave the impressionable with the idea that nothing can be done unless the curvature of the earth is taken into direct account, while we older dogs know that a large number of projects are done on a 5000/5000 basis.

Thank you, Mr. Mayer, I wrote this part of the class from a geodetic surveying perspective and didn't include a discussion of local control systems for smaller projects.

There doesn't seem to be much interest but I'll continue to post the other modules anyway for those that are interested.

I think I'll post the second one in a new thread so that any comments will be specific to that one instead of adding it on here. Or is there an appropriate protocol on this site for this type of situation?

There is definitely interest. I know a rookie that needs to read thru the whole series along with his boss. But it will have to wait till Monday.
Thanks,
James

Iƒ??m looking forward to digesting the material. Iƒ??ve been in the Operating Engineers (Local 701) here in Oregon since 1974. For the last 10 years Iƒ??ve been building 3D construction models, making use of GPS technology (via Topcon) beginning with job site layout and grade checking. We are now using machine control on dozers and excavators with impressive results. For the entire 10 years Iƒ??ve asked everyone Iƒ??ve met to explain the technology. No one has had all the answers. Many of the sources such as the dealers (the only way those of us in the field can interact with Topcon) have a basic presentation but that's all.

We have a dealer that sells mostly GPS but also some robots that doesn't know how to properly setup a robot. He missed the whole part about using the leg adjustments to get level. 🙂

Traffic on the site is lighter on weekends. Wait until Monday.

Fortunately when the dealer brought our robot last winter he did have the leg adjustment info. It would have been good to know years ago but it made my day to learn it. When I was younger I thought I'd get smarter as I got older. Instead at 65 I keep discovering how much I don't know and have yet to learn.

An old quote from years ago.
"Every day I wake up with the knowledge that I am smarter today than I was yesterday... but that is only because I wake up and realize I wasn't as smart yesterday as I thought I was!"

Definitely interested in looking at the rest. Please post thanks.

Great first chapter. Looking forward to reading the rest of the them. Thanks for sharing.

Thanks for posting. Downloaded the two chapters, looking forward to the rest!

Good stuff Tom.

Is that picture on the top of p. 6 from the Bay Bridge project?

Definitely interested... as Mark said, not as much traffic on the weekends.

Thank you for sharing. I am always adding to my library. Both in digital and hardbound formats.

That picture is an http://www.snopes.com/misaligned-bridge-photo/&apos ;">old thing that has been around for years. It isn't any particular bridge at all.

Ha, Evan..... No, I got that from a presentation by Dave Doyle or Dr. Snay of NGS.

I did, however, work on the geodetic control for the Bay Bridge project and a bunch more in the SF Bay Area and all of them got built without the page 6 problem.
