There’s been a hot spot of discussion today regarding the use of hand drawn contours to fix an unsightly surface. Since the original post in the NG is being ignored, I think it’s worthwhile to open the discussion here. Read on and join in the debate.
The point of contention is that in an existing ground surface, adding a polyline at elevation to smooth a contour is a sin. The inquisition claims that this isn’t fixing the surface, but is destroying the integrity of the data. They think the user should be fired.
Isn’t adding a breakline (or contour) fixing the surface? If I’ve been to the site, and I want to make the surface more palatable to the reviewing agency, why is adding a breakline (or contour) such a cardinal sin?
I think the hard-nosed crowd is missing the forest for the trees on this one. Yes, I agree that the data should drive, but I also operate in a real world where sending out a $1000 a day crew to add few points versus adding a breakline to make the contours look “right” to the reviewer is an easy decision.
We’re talking dirt. I spent a day shooting a site with level and rod, calling off 76.64, 76.58, 76.55, etc. (It was Amarillo, TX.) At the end, the chief hands me field book to enter at the office.
76.6 and a line drawn half way down the page. Then 76.4 and a line for a few shots, then 76.5 and a line.
I looked at him, kind of stunned. I worked hard on all those readings! His comment? “It’s just dirt college kid.”
Would you say that was wrong? Would you say that collecting decimal places on dirt is wrong? Then why is adding a breakline (or contour) wrong? Time to step back and remember, “It’s just dirt.”
Fire back in the comments!
