That was my next step, but it's raining hard today, and the week looks like rain also. Should I shoot their points with normal GPS or localized to Grid to Ground?
Have you checked the calibration of your EDM on an established calibration baseline?
Here are screenshots I recorded when orientating to their control. Looks like all shots were short, due to no -0.15 negative.
My TS scale factor was set to 1.00000
Oh boy...you better take some extra precautions before you get yourself in the ringer. I would be checking to existing improvements before I take off with their control. Wouldn't be the first time I've seen that happen.
Yeah, I know. I don't want to shoot anything on that sight till I get this figured out. Is it me or them...
Have you checked the calibration of your EDM on an established calibration baseline?
No, but my instruments were both calibrated. And I shot their points with both a TS07 and TS16 at a scale to 1.0000
I would consider stripping his name and ls number from the report you posted out of general courtesy.
I would not appreciate being put on blast with what was probably an internal document.
This might help, with my CAD software, it is set to a scale factor of 1.0000
And when I pick a building corner etc.. from CAD it matches the blueprint coordinates exactly
Sorry about putting that doc out there, just wanted to show the scale (Fixed)
I did a quick calculation at that location. You're using the wrong system, you're confused by the scale factor of 1. The grid distance of two state plane points 950.00' apart should measure 950.14' on the ground.
I don't know that software that you posted a screen shot of, but I'm assuming the 1 scale factor means no adjustments are applied to state plane.
I'm not sure about your horizontal but you have a vertical issue also. You shot between 48-45, 47-46, and 47-48. With the trig elevations looking fine 0.02' being the largest difference. But when you staked out 47 you got a fill of 0.18'. Not sure what the occupied point was for this stake out shot but the elevation of 47 agreed with both 46 and 48 and thus 45 previously. It shouldn't miss on this stake out shot unless you were using a control point not mentioned yet to stake it from.
The stakeout was a GPS shot on their control point, which I forgot I did, until digging up the records
Is 0.18' an expected miss for your GPS equipment? Using the equipment I'm familiar with, missing that far in elevation is an indication of something wrong.
So are you implying the TS is not in the correct scale factor? I was taught to always keep the TS at a scale of 1, so when things are field measured with a steel tape things are going to line up.
I understand state plan is a grid system and a TS at a scale of 1 is ground. That's why I do a grid-to-ground conversion with GPS.
Is 0.18′ an expected miss for your GPS equipment? Using the equipment I’m familiar with, missing that far in elevation is an indication of something wrong.
No, I have a Leica GS18, I would have to stake that point out again to be sure, as of now Im trying to get my horizontal dialed in first.
When you're shooting ground with a TS is your scale factor always 1.0000 correct? I'm not trying to shoot to the grid if I were then I would change the scale factor.
