Hello
I am quite new to TBC and have a question regarding the transform points feature.
When out in the field i have set up the TS and shot points from E:1000.000 N:5000.000 E:100.00, when i survey the 2 control stations with the GPS as observed control points 3 times each then average them to get the coords and get them back to the office i seem to always get a vertical residual error when i transform the points to the GPS shot points, is it something i am doing in the field to cause this error? Any help on this would be appreciated.
Thanks
Stevie
