I agree Adam. The somewhat “obsession” with accuracy in today’s surveying world sometimes just astonishes me really. We’re all doing a million times better work with the most unbelievable equipment ever produced and for some crazy reason many surveyors and lots of clients are passionate about getting distances within ridiculous tolerances.
1:50,000, as Sean stated, is basically impossible. Sure, you can get closure loops and equipment to”say” it’s that tight, but in all reality, it’s not. You can’t plumb (and keep) any base pole, rover pole or EDM rod to that amount. No one can drive a spike, nail or rebar to that specific of a distance.
I realize different people work in much different areas and deal with different “standards” of sorts that are outside each individuals State board regulations and I certainly respect that. I have worked most of my career in very rural areas. I follow a lot of deeds that have NEVER had a distance on them, period. I’ll establish lines across multiple ridges and valleys of 2000’ or more. I ran hundreds of thousands of EDM loops and prayed to get em within 1:5000. Now, with the Javad LS, I am getting those lines within 0.1’, or better, for each point. That is truly amazing and all of us in our company are proud to sign it.
Now, that’s not to say when I’m working in the city closest to me, and it’s a 2 million dollar lot a Meier store is going on, I’ll accept the same tolerance. Those will, and should be, much much tighter and the LS will attain that, with the proper profiles and settings and multiple shots.
This is obviously nothing against Tyler for asking the question. He’s simply trying to find out how to get what his client is asking for, no matter how unreasonable it is. Again, just think about the “math” a moment - very possibly driving in a 1/2” or 5/8” rebar for the corner, but the client wants accuracy to 0.002’ per 100’? I’ve had this post “ in my craw” for a while and this just seemed like a good time and spot to post it. In my humble opinion, far, far too much time in today’s surveying world is spent obsessing over a few hundredths of a foot.
Good luck to you Tyler!
