Prism Constant

I have taken about 100 shots with the wrong “prism constant”. The traverse work was done with a “0 offset prism” and the locations were shot with a -23.1mm offset. There were also some random shots taken in reflectorless mode that were interspersed within the bad data that do not need adjustment.

When this error was made in the past it was corrected in LDD by converting the raw data file to a FBK file and adding the command “Prism Constant -23.1” in the appropriate places and importing the FBK file to create the correct coordinates.

I cannot find how to make this adjustment with the Carlson software. Can you point me in the right direction to solve this issue using Carlson?

Thanks,

I've got the IntelliCAD version, so I'm not sure if this will be the same:


Survey > Edit-Process-Raw-Data

in the next dialog

Edit > Modify Measurements fill in the correction on the second line "Add / Subtract Distance"

Thanks Peter, it's pretty obvious when you know where to look. I just didn't look in the right places.
