> I have noticed a few posts concerning people doing solar observations for azimuth determinations. How prevalent is this nowadays? I thought with ...

How lazy are surveyors to reference to some ethereal place called North and not really know if their survey is truly related to it?Ignorance is a poor...

It'll take enough people asking for it to become a reality, but all the technology is there for a total station to be able to spit out an azimuth in r...

For the purposes I've used solar observations in the past, DUT was superfluous. My solars always agreed with GPS derived bearings to within 15 arc sec...

I get time from the handheld GPS too. It's kind of a one stop shop for information, other than the ephemeris.

I drew up a couple of area charts like that for figuring out how to program a predetermined area calculation a few years ago, but nothing that thoroug...

I'm doing it using Carlson Survey 2013 with IntelliCad 7. What software do you have?

By the way. No flaming from me. Your work may be excellent, I simply disagree with what I think you are suggesting.As to the tape and transit vs. GPS,...

Linebender gave great answers. The elevation factors combined with the scale factor can easily exceed 100ppm (which is equivalent to 1:10,000 - tomayt...

I've never tested this, but I've always wondered about digging a hole a few feet from the water's edge deep enough for water to fill the hole, waiting...

early release of Carlson Survey 2013 over Icad 7.2 had issues with images. That seems to be resolved now. No problems with coordinate values. I do hav...

I agree with Al. It can be done OTF. I mentioned uniterrupted data. You can be walking around from point to point, as long as the receiver doesn't los...

The L1 is used once the ambiguities are fixed. The L1 is a shorter wavelength than the L2, which makes it more precise for positioning. Using ONLY L1 ...

I really enjoyed it. I knew a little about invar being used in surveying for chains, level rods and subtense bars, but never really thought much about...

I think flogging needs to make a comeback for anyone that writes a spiral into a ROW deed (just kidding). But it is so unnecessary.:good:

:good:I agree. It is a found distance. He just put markers there to perpetuate what he found, but he didn't set anything from a calculation.
