Triumph2 problems

I set my Triumph2 over 2 control points of another Surveyor for Pa coords and good elevation for a project. downloaded the 2 setups on my pc then DPOS and OPUS the results. when i inversed between the points, both results are very close but the points are 13' short. Any ideas what might have happened?

The azimuth between these two points are 313deg. 42' 40.105212" and the distance is 53.43'. (If I read the report right. The format looks a little odd pasted in this field)

What does the Opus reports look like and what is the azimuth and distance that the other surveyor gave you?

The inverse is N 45 43 45 W -53.3343'. The Opus report is within a couple hundreds, am I converting it incorrectly to feet? I thought I was using the PA coords.

The reports you posted have UTM and Spc in meters and they are only separated by a space. I converted your SPC to feet and entered it into my LS in PA South Zone and then inversed.

Your residuals look ok. If you are coming up with 13' of error between what you shot and the other surveyor I would assume one of two things. Either the points you were locating were not the same or the coordinates he gave you are not correct.

When I converted to feet and entered them in my old 48 and inversed that is where I got the large area, the points are the same, but I think his one point maybe have been run over.

So I'm confused with were the 13' comes in. Is the data from the other surveyor 13' different than your static solutions or is it just a difference with what you get from your old 48?

It sounds like a problem in the meters to feet conversion in your 48. I converted it myself by multiplying by 3.28083332904.

FWIW I had a local surveyor here have the same problem with the conversion in an App. He had not double checked the Apps math. Once he had the correct conversion factor all monument sheets matched.

Using international feet, versus u.s. feet, makes a bigger difference in the Northeast part of your area period in the southwest part of the area closer to the origin it makes less difference so this is strictly a variable.
