why do you need to enter total station or target height? people i work with have never done this. In my scenarios i am given co-ordinates with heights could that be the reason why, thanks
The height is a measurement down to a fixed survey marker (eg a nail in the ground) that the instrument/target tripod has been set up over. If you were to return to the same marker points at a future time/date, with new tripod setups, the heights will be different. The heights need to be known so that multiple sets of survey data, taken at different times, will match together.
For what it's worth, I was told by my local Leica distributor to leave the height of the instrument as zero (and this is exactly what I've been doing for the last seven years using a Leica TS15/TS16). It seems to be able to calculate the instrument height based on the resection points.
@@HunterGeophysicsAustralia I do the same, also I don't add heights to my targets. I just assumed the ts already knows the height of it from when the control was setup. But I think this video demonstrates setting up off a resection which isnt retros (secondary control).
@@NasirIKLBP yup. I recently bought an MS60 and have been scanning the ground surface as well as other reflective targets I’d previously put around work sites years ago with a TS16. Everything lined up perfectly without entering the instrument height. So this (leaving the instrument height as “0”) definitely seems to be the correct method.
In setup_resection free point we don't need to put the height for the total station because it should be unknown point
If you're doing 3D survey, you will need to enter the instrument height in resection to determine 3D coordinates (N,E,Z) of your free station.
Is it any full video on site survey using leica
THANK YOU. VERY WELL EXPLAINED IT!!!!!

@@anivegmin I think he doesn't add heights as he is setting up off a resection using retros (secondary control)
How do I know the height of the instrument?
Measure it with a tape measure.
