Here's the last bit of that chat with Google AI. Same disclaimer, but note the difference between a datum name ant its mathematical treatment. S...

Okay, now, I'm not a surveyor nor a GIS guru. I just do math and research its applications, of which surveying and GIS are vast reservoirs. On the r...

Check the superseded data for PID AI0952. Which CORS96 position is the standard?

@lurker Well put; we're all different. The formulas stem from the concepts, so there's no reason to not know both, but what to apply is an individu...

@mightymoe Well, yes. But, if you're east of the CM, convergence Angle will be positive, if you're west of the CM, It will be negative. Using the...

@murphy Just be careful with those rules for adding and subtracting. Convergence angles and declinations are signed numbers for a reason and formul...

@john-putnam had it close to right, but Convergence Angle should be subtracted, not added. Part of the confusion stems from trying to remember add or ...

@mightymoe Yes, extreme convergence angles is one problem that LDPs lessen but don't completely solve because there is no total solution. Coordinat...

@holy-cow Fascinating. I graduated from college in 1967 with a mathematics degree. The physics department was building a computer which I wasn't al...

@norman-oklahoma Should someone verify the coordinates associated with those new monuments?

Exactly and well stated. What the (0, 0) is really saying is that we just multiplied state plane coordinates by a factor to create ground coordinates....

The ground projection is actually scaled around 600,000.0000, 0.

What you did beats a calibration by miles.

@holy-cow The sun does that only twice a year no matter where you live. We've learned to cope with it here. The curves in our roads reflect politic...

@mightymoe Oh, I see. They're on different curves. Thanks, Moe.

@mightymoe But won't you get the same answer whether you inverse from PT to PC or from PC to PT? And except for the negative sign, won't you get th...
