Topcon ES 105 5" total station. I would rather have a 3" instrument. Specifically, a Leica 3" instrument. The office has a 5" or better tolerance on d...

@john-nolton?ÿ Thanks for clarifying the math! In the past I remember situations where the FSD angle was greater than 180?ø, and some additional math...

Where do you get the 30.5" from in the?ÿmean D&R column? Also, I remember doing some additional math if the direct angle to the foresight was >...

@nate-the-surveyor?ÿ Hopefully the many answers won't be too far behind them!

@lukenz?ÿ I'm curious about the wisdom of Topcon for including the geodetic distance in their point-to-point inverse output. How is that data useful ...

Is geodetic distance synonymous with grid distance? Baselined as in checked on a calibration range? In 1994 we used a Topcon GTS-4A for an FDOT proj...

We had good results so far on our current project with total station distances vs. GPS -derived distances. Points 1 to 2 and 2 to 3 were both within a...

Those are my words. They just want something official like an NGS point.

@mightymoe?ÿ All kidding aside, I initially agreed with management on the validity of their argument, but the next day I reverted back to my original...

@jed?ÿ Interesting method. Thanks for sharing!

@jed?ÿ I can't visualize how you only have to go one direction. We haven't started the traverse yet. It will go a quarter mile north, a quarter mile ...
