First Monday morning question from an engineer.
Posted by Norm on December 10, 2018 at 1:15 pmIs there any chance that you were given the option to enter in a scale factor when you converted to state planes? When I measure the distance between stations I am getting a distance of roughly 99.9957 feet.
Sigh
I wonder what the precise measurement was compared to the rough one?

i’d tell him that if he hadn’t been in such a hurry that you coulda sent the crew out the day after the rods get their weekly tip honings.
Ah, but what if it is consistent? What if there is a case where two sets of data exist for the same boundary project and two sets of numbers. One set of distances is consistently equal to 99.9957 percent of the other set. This will show up on longer distances such as the ones common in PLSSia. Due to rounding errors they won’t be exactly 99.9957 percent, but very close.
Trust me. I have seen this happen on numerous occasions. So, be careful out there. $#** happens!
The complexity of engineering tends to escape surveyors. That .0043 could induce quasi-pietric stresses in the spiral decommutator leading to side fumbling along the ambifacient lunar vaneshaft????…it goes without saying that no one wants that!!!!

There are no dumb questions, remember that. What if this was a 5 mile road project and his measurements were consistent? Wouldn’t you want to know?

Search for turbo encabulator. There are some great data sheets and video presentations. That joke and variations have been around since 1946.

The Retro Encabulator is my favorite, the presenter held it together till the end, but you can tell he almost lost it a couple of times. I wonder how many takes were needed. I think it should be updated with acronyms taking the place of technobabble.
We have a Communications Engineer because the communications in a statewide Fire Department is complex. He was tasked with teaching us about the HT radios (Handy-Talkie is universal FD jargon, what the rest of the world calls Walkie-Talkie). I don’t think he ever spoke an English word I understood, very smart guy though.
I learned how to use the Mobile Radio in the truck just by peppering him with questions, helps to have a thick skin when asking a near genius level engineer questions, they can be brusque LOL. I learned it that way. You put in the CTCSS tone for the repeater that you are near, Local Emergency Command Center frequencies and Command frequencies have repeater tones assigned. TAC channels do not. When you key the mic the radio transmits a tone (can’t hear it) which opens the repeater which broadcasts your message a lot further.
could vary that amount due to arc or straight measurement of stationing /chainage. or slope/plan chainage. many possibilites. none of them matter if they are handled correctly. ie a consistent chainage equation used by everyone. that’s why we have 6D strings! but yeah – 0.3mm get over it!
Turbo encabulator, retro encabulator, quasi petric babble?
Is this some kind of joke from before I came into being like Who’s on First?
YES!
BTW, what was the temperature and when was that measuring device last calibrated?
That looks like a flat measurement on a curved earth.

Just so you know, they were expecting 100 ft. LDP grid stationing to equal 100 ft. state plane grid stationing on their map. Just like they would have expected ground to equal grid. Most engineers still don’t believe the earth is a globe and they want surveyors to keep it flat.
Tell him to come back and ask after he’s come up with the exact measurement, you can’t deal with roughly.
There are no dumb questions, remember that. What if this was a 5 mile road project and his measurements were consistent? Wouldn’t you want to know?
Nope.
5mi x $1,000,000/mi x (1-0.999957) = $215
Never estimated a project that well.

Kudos for the state planes reference. A long time ago I thought it was state plane, of course autocat made me realize it’s really state planes.

It makes a difference in writing boundary descriptions. Think about that for a bit.
