One RTK observation is inappropriate for control. I agree.

But always make sure you are in ground when surveying. Thanks for your advice.

Your issues are measurement techniques, those need to be tightened up, both GNSS and TS. That's only partially true, because I have complete contro...

okee dokee Thanks for the discussion, Norm. I enjoyed it.

As far as whether you want everything referenced to the grid? That's up to whoever is running the project. Do you have a preference when performing...

The difference in the BS is 6" observed and the tolerance is set at 5". I think it may be trying to tell you something. It may be trying to tell m...

@field-dog I don't know what field software you are using, but many of them will allow for computing scale factors for total station setups/observat...

@field-dog Are you having trouble making your TS match up with your GNSS? Yes. In most cases.

tolerances are specified outer limits of acceptability. I never thought of it that way. I thought I was specifying the maximum deviation from the m...

@mightymoe Thanks for checking out the SPC zones. We use the Florida SPC east zone. We typically set control points two hundred to five hundred feet...

But sometimes everything is in grid because we're working on a small site and the combined scale factor is so close to 1 that there is no discernible ...

If you wish to survey in State Coordinates your DC should do all those calculations for you as you collect data. All of our jobs need to use SPCs. ...

@jitterboogie I don't know a thing about LDP, but I found some good information about it.

@holy-cow No mountains here.

@holy-cow Then it makes sense to compensate for the difference in elevation between control points.

@jim-frame I don't select Grid to Ground on my DC, so it sets its own SF. If I'm mixing RTK coordinates with total station coordinates, don't I want ...
