There seems to be two USACE lakes in that county, Pomona and Malvern. You could try the project offices at each, depending on which it is closer to. I...

Also, there is an EDM Calibration Base Line (CBL) in Ohio (Culver-Davies) that consists of four pedestals rather than ground marks. Very nicely constr...

I have used many of these types of monuments on deformation surveys. And I have built quite a few. I installed two on my property, intervisible. One I...

@cgi2099 No, as I said, you can login to the Webui on the receiver over wifi from a phone or laptop. You do not need access to start a base.

@cgi2099 No. The rover radio is receive only, and the base is transmit only. That is why I like using cell, I can login to the base (if I have a stati...

I should add that is the way for anyone to start a (newer) Trimble base without using a data collector, just using a phone or laptop

@cgi2099 In the webui (connect to the receiver via wifi, usually 192.168.142.1 unless you changed it): 1) under receiver configuration, set the a...

@cgi2099 Yes, both the base and the rover need internet access. Not as hard as it sounds (assuming you have cell coverage). One way is to use in...

I would just start the base using the webUI and set it to transmit RTCM or CMRx. The rover will receive these corrections (over cell or radio) and out...

A related question...how many on this board have actually done planetable mapping? Probably only a few old timers. I did some on a Corps of Engineers ...

There is a difference between "corrections" and "adjustments". LOCUS does apply various corrections, and can also perform adjustments. A typical sh...

I have seen that before...specs written by an engineer with no understanding of accuracy and significant figures. What they most likely mean is they w...

That's very cool. I note that it is the vertical angle method, which did not require accurate time but was influenced by refraction and errors in the ...

Also look at SNIP caster. if you have any questions about how to set it all up, I would be glad to help

I do not use TBC to process level data (or total station data or RTK for that matter, only for post processed static GNSS). By the way, dini comes f...

I run a lot of levels. Multi-section rods are OK if running in a flat area. Once you start mixing high rod/low rod, errors will accumulate. I have thr...

So if it is just an azimuth mark it does not have a position. The "box score" shown only lists an azimuth to it, no distance, so no position was compu...

It keeps getting larger every year. There were 7000+ attendees this year. BUT, I saw fewer people that I know than in past years. Disappointing in tha...

Makes sense, Jeff, thanks for that. Weird, though that the Trimble run VRSNow does not use that terminology.
