Adjustment to 2017.5 epoch help

  • 1.  Adjustment to 2017.5 epoch help

    Good morning,

     

    Can someone assist me with adjusting data to a 2017.5 epoch in TBC? New to this, trying to figure it out.

     

    Thank you,

    Aaron,

    You'll want to update the coordinate system in the TBC project.

        1. At the bottom of the screen select your current system. 

        2. Select United States / NAD83 / CA SRS - Zone 6 (probably)

        3. In the pop-up menu select Convert Global Coordinates.
