We are not really surveyors any more.
A surveyor used to measure lines. I mean, with a chain, and a compass. Hack out true line, or a parallel offset. Compass and tape it.
All the crew and spectators saw measurements occur.
Then, a surveyor used to calc it all up, with lattitudes, and departues. With a book of natural sines, and trig functions.
Then, he’d draft it all up.
That was kind of the end of “true line”
Hand written bills.
Draw out whole cities, on linen sheets. Set whatever mons were available.
Then, came theodolites, and TRUE line was rarely ever fully run. Things were done from hilltop to hilltop. Again, books with sines, Cosines, and Tangents.
Run Traverse, shoot the corners, and CALC the true lines. Still actually MEASURING angles, and distances. Chaining. Chaining nails. Traverse nails. Actually SEEING the number 200.00 in a field book. + 23.75 feet.
Or, 200.00 ft @ 3å¡ on the abney level. + 23.75′ in the book.
At this point, all new crew members actually saw measurements happening. Angles. Were wound up 2x, or 4x or 6x.
Math was adding, subtracting, sexigesimal digits.
Then, it was all done on a drafting machine, to generate a worksheet. Things were re-gurgitated, onto paper, for analysis.
Then, coords were subtracted to get northing difference, and easting difference. For field staking.
Corners were set. Life went on. But, all the crew saw actual measurements occurring.
If the crew member was only chopping brush, He SAW measurements occurring. (then went back to brushing)Then, came Data collectors. And total Stations. Measurements were occurring. But, they were MORE transparent. The laser did the distance. EDM. 1974, 1976. those EDM’s were awesome!
Then, it was all put into a TOTAL STATION. dual axis compensating. WOW!
Then, GPS.
Now, REAL TIME ON THE FLY GPS!
We no longer see measurements occurring. We only do it “via inverse”.
BUT something good has come back!
TRUE LINE again! box tape, 3.2′ north, to line.
The next generation, is not really going to know how to measure. And, how much work a survey is.We are fast becoming electronic surveying gizmo workers.
Is the next generation of surveyors going to understand a “Ground Distance” in the same way we did?I have sent out several plats, and bills, where I NEVER even printed the final. It was a bunch of ‘lectronic bits. A PDF file. And, the money was sent to me. Someday that may be just an ‘lectronic fund transfer! For some of you that has already happened!
Where are we going?
Another surveyor recently said to me: “The pick, and shovel, and briars, and ticks will sustain surveying”. Because, the general public does not want to FACE them!
So, will the very things we avoid, keep us going?
Recently, I got a job, because a GIS person, thinks something is wrong. I think they are right!
Life goes on.
But, I am concerned. We are loosing our connection to the actual nitty grit of the old ways. IS that bad. I don’t know. But, I do like the new ‘quipment! and I do like the creek when I am done.
God Bless everybody. And, may your scale factor be correct!
