Hi Everyone,
I was using a Topcon GTS-229 Total Station. I measured two known points with a Trimble R8 GPS. One of these known points measured with a Trimble R8 GPS was the one on which I setup the total station. The second point was for the backsight position. While doing the backsight I clicked measure on the total station and during the survey I did not check the reading. But now back at the office I have noticed that there is a discrepancy of about 1 meter in comparison to the Trimble GPS reading. This has resulted in all my measurements being incorrectly oriented by about 10-20 degrees.
Is there a way I can correct this mistake at the office considering that I cannot go back to the site and redo the survey? I have attached the raw data files that are incorrect as well as the correct coordinates in case someone wants to see the data together with a Google Earth plot of the incorrect data.
The blue lines are our traverses based on the incorrect positions. The correct positions should have the most western blue line move to the orange position. So it looks as if the coordinates must be rotated clockwise by 10-20 degrees.
Thanking you in advance for your help.
