Hello fellow Brethren...I am preparing the lectures for my fall class, Intro to GIS and GNSS. I would like to update some of the pics in my slides. I am looking for really good and really bad GPS set-ups, data collection, etc. If so inclined, please just reply with the pic or feel free to PM them to me. Be sure to include name, location and I will be sure to give credit if you want. Especially if you are one of those "influencers".?ÿ
N10,000, E7,000, Z100.00
PLS - IL, MO, AR, KS, MN, KY
This is the epitome of how NOT to do it.?ÿ I stopped when Driving past this setup, and as luck would have it, I knew the surveyor.
Luckily, I drove farther toward my house, and sure enough, see the crew completely out of site from their base, collecting data still unaware.
I roll down my window( which we all know invokes the surveyor knee kerk reaction look of "what the F do you want..." ) and ask " Hey guys, is that your base across the valley?"?ÿ "Uh Yeah, Why??"
Me:?ÿ The GPS base is leaning over, but stable, and lucky thing I found you.?ÿ I saw it that way about 20 minutes ago....Here look at the photo.....
Interestingly, the peak-to-peak didn't even include the expected elevation, so I went back and did an eccentric setup, leveled to the mark, and found it almost exactly 1 foot off the RESET value when using typical geoid offset for the area. Somebody blew it.
to be fair, youre actually getting a section corner, I'm just trying to get the TOP of the waterline the Utility wonks can't seem to spare any time or effort to give me a vertical shot, so I just dialed up the tiltometer on the R12 and Bam!
Keokuk the city is not in Keokuk County.?ÿ But the town of Webster in Keokuk County, not Webster County. We had a thread once upon a time here about such mismatches.
It is an R 12 after all.....and great skies north west and south....east kinda sucked.... ?????ÿ
And the auto error was kinda high, but it's just a locate for Telco, and soon an investigation for the locators who have been scamming the majority of the people waiting for them.

Me:?ÿ "Don't worry, I already told Tom when i stopped by the office."?ÿ
Them: S^%&!!!!"
When I encountered something like this, I used to just get out and hold my hands over the antenna for a few minutes.?ÿ Didn't take long for the crew to come driving up fast and furious to see what what wrong with the base!
