Didn’t Washington and Jefferson both write in their journals about the possum. They were both surveyors. Also Taft don’t know if he was a surveyor but...

@jbw That sounds great. Yet my daughters think I grew up with dinosaurs lol. Hey so glad you made it. I hope to see you there soon myself.

Glad you did it for sure. Gives me hope. I am a decade above 40 so what you are saying is there is a chance. Congrats.

@mightymoe You are so correct. That those old timers understood and did math Longhand without a data collector without a calculator even. Maybe they h...

@mathteacher oh I didn’t take it as being snippy. I don’t take things personal at all. Value your input tremendously. We are all here to learn the wa...

@mightymoe well ground has its own issues as well. Every time you set up a total station you are technically defining a new plane as gravity is not th...

here ya go @mathteacher This is what I was referring to on population it’s not just that but it was utilized within the design all within the first...

I tried telling the folks here to adopt LDP’s for our state. But they wanted to keep it the same. So we end up with north and south like always and of...

you are correct on the math part. Go and watch some of Michael Dennis webinars on the new state plane. They weighted it and tilted the planes to achie...

I believe it depends on project specs on if you will need to scale between grid and ground. Unlike NAD 83 the map projection were either tangent or s...

@mightymoe OK my Bad. I was looking at deriving a combined factor at each of the two points in your scenario. You would have a lat long height at say...

@mightymoe if I gave you one lat long and ellipsoid height you have everything you need to compute the cf no need to list that. I do see your point. B...

@mightymoe In some states it was written even back in the NAD27 days that if a monument GS was within a certain distance then a tie to it needed to be...

I was not hit by the paywall. It just didn’t get me. Great read for sure.

@mightymoe which NAD83. NAD 83 is the lat and longs. That’s the datum. Then you get state plane or UTM or LDP based on that LAT LONG. Yes in Trimble y...

I use Carlson cad in office and Trimble equipment in the field. I think what you are seeing is this. Rounding. So before I wblock out what linework I ...

@mathteacher in reports in Trimble if you are straight up state plane it will show 1.000000. If you scale to ground in state plane it will show the or...

@norm lol you are so correct. I have seen just about everything. Here is one for the Trimble folks. A guy had some grid coordinates the office assign...

I don’t think 1 means ground or grid. It means 1 to whatever you are in when using Trimble. But you don’t key in the c/f in Trimble. You key in a gro...

@mightymoe oh gotcha. Yeah that chat gpt thing didn’t make a lot of sense on that to me either. I use no projection no datum when I must do site cali...
