No I did not, I dont know what system they are in, the surveyor reshot all those points

I want to be able to measure the ground distance with a TS at a scale of 1.00000 so they are true ground distance. The surveyors shot in the control ...

Sorry this

and this

Mabey this helps

So if I change the scale factor on the gun to 0.999853 I should line up with survey control? For example- if I shoot in the grid lines for the project...

Sorry about putting that doc out there, just wanted to show the scale (Fixed)
