Can you advise on a technique in TBC... (2.8)
I did a local topo survey with an S6 as our VRS station was offline. I set two control points st1 and st2, later that day I gps those two points in... now I want to transform my survey onto WGS 84.. you think TBC will let me... I can do it in TGO but not TBC.
Here is a link in my dropbox to my job file and the two control points in a csv file that were later GPS'ed in.
The transformation is from the st points to the russ points
st1=russ1
st2=russ2

This is a straightforward excercise I cannot get the logic of TBC to do it, it wont let me do anything with any survey data....it just stays gray... ( even if I import a csv file of the survey, it wont let me edit or transform those points.)
I can do this on access on my TSC3 controller in the field, why should doing it on a computer in the office be any more complicated.
Thanks
Ideally, you would have used the same point numbers for the control in each file. That would merge the points automatically.
If not, change the numbers to match, then merge them. After that, erase the assumed coordinates for the control used previously. Then "F4" re-compute. That should take care of it.
Thanks, I will give it a try.
Thanks, got it to work, I would have preferred a straightforward transformation where you choose what points the transformation must be done about and also the scale factor, as this merge option seemed to of introduced a small scale factor which adjusted the point co ordinates by about 5-8mm , which isn't an issue though.
I also had to adjust my assumed back site bearing to the correct value to get the orientation right.
Thanks for the advice .
