The DC file now relies on the Survey Software to add this data to your slope distances which i think goes against everything i was shown in the beginning. I was taught very early on in the peace that you always had to have the Prism Constant set on your jigger so that you get the correct answer. The DC is the raw file without any calculations being added to it, where the SDR file has calcualtions added to it therefore not the raw file. I also downloaded an SDR file of the same job and compared those 2 files and the SDR file DOES have the prism constant added showing in this case a 31mm difference between the 2 points.

This mean they are the RAW observations without the correct adjustment being done to those distance on the Total Station. The Trimble TSC3 DC file that gets exported from the Jigger DOESN’T add the Prism Constant to the slope distances. ![]()
