-The first possibility is that a point was disturbed.
-Secondly, check your data to be sure scale factors, projections, and datums are EXACTLY the same.
- Check the specs on your prisms and which ones were placed where.
- Of course, consider operator error, poor instrument or reflector setup.
The solution is not obvious given the limited data.
The old carpenter's saying, "measure twice; cut once" can be very important in surveying as well. Make sure two sets of observations agree before acting on them. If they don't agree, take another set of observations.
Good luck,
JAC
Thanks J. Anthony Cavell
as you said measurements, so we have measured twice the control points but in both we faced mass mach location of objects were in the first location that were surveyed first.
Mr. Salem,
I'm sorry; I don't understand your meaning. Please explain to me again.
