Base point correction

[Mark Wheeler]

I am new to utilizing LS (rover) with T2 (base). I had an old worksheet in my truck and plugged in a point currently renumbered in current point file. This point is 240' easterly of the actual site point. A half mile from the site I discovered it staking to a another traverse point. I finished my locations and downloaded the base data from the T-2 to the LS. Is there a simple way to correct the session by editing the base point? What is the best solution to rectifiy the incident within the LS (versus downloading the new points and shifting them in CAD)?

Use MLocal.
Go to points screen, highlight point, tap chart looking button, tap icon that has 2 planes on it, enter known coordinate.

Just a comment. When you start your base, you always get a 2d delta. If you pay attention to this, you'll catch this kind of blunder. (Note to developers, it'd be nice if this had a little pop-up, excessive 2d delta, if this number is larger than maybe 30', or so)
This could prevent future users from this blunder. You can override this popup, but you've been warned.
Adam has your answer.

Recently, we had a very excessive 2d delta. 40 miles or so. It could popup and say "excessive 2d delta, override, YES....NO."
it had the base lat Lon from a prev job.
How much error does a 240' error in base location introduce?

On our job with a 40 mile 2d delta, we started our base, but it would not give a fix.
It's a blunder, we all are subject to, potentially. We went back to base, and restarted, which was when we discovered the cause.

Thank you.

Adam, I am not sure what you mean by the chart looking Icon on the point screen.

It's above the dpos button. Maybe below. I don't have it in front of me.

Thanks Adam,
I had tried to find M-Local prior to sending points to DPOS for Base Rover processing. Once I did the menus showed up. Worked fine.
