Reply To: Calibration


I’ve attached back It has a trv file you can open with the traverses I used.

Your Objective
If I understand what you are asking, you don’t want to use a calibration created by calibrating from Field-Measured to Deed-Points. Instead, you want to use a calibration that mimics a manual translate / rotate of the Field-Measured to Deed-Points.

What’s the Difference?
With a manual translate/rotate, you control the transformation from Field-Measured to Deed-Points. If you had calibrated from Field-Measured to Deed-Points, the calibration would have determined the transformation. One of the characteristics of your manual translate/rotate is that there is no scaling. Either way it fine by Traverse PC. You are always in charge of making decisions like that.

What not to do then
That being the case, you do not want to create a calibration From: Field-Measured To: Deed-Points.

What you do want to do
Instead, you want to do this
1. Create a duplicate of Field-Measured (TPC names it DUP-Field-Measured) with its own points, and translate/rotate that traverse to Deed-Points.
2. Create a calibration From: Field-Measured To: DUP-Field-Measured.

Now, the calibration that is created, mimics your translate/rotate.

Let us know if this is what you are after.

You can also play around with creating a calibration From: Field-Measured To: Deed-Points and turning of scaling. Might also get you what you want.
