Add label altitude to that station and use it.

Hi all,
How to 'fix' the survey station point (to morph the cave plan) having only 2D
coordinates?
Using the radiolocation we get (with quite good accuracy) the station point
give you the relative altitude at the end - just use that.

Adam,
Radio-location can give you depth but accuracy is not too good.
How have your surface positions at the entrance(s) and the radio location
been determined ?
Professional GNSS (~3cm), DGPS(~1m) or hand held (~3m) ?
I have radio-location fixes at the far end of a system to control any

Hi all,
How to 'fix' the survey station point (to morph the cave plan) having

Using the radiolocation we get (with quite good accuracy) the station
point position which is about 150m beyond the estimated location we
get from surveying. So now I wanted to use this position to
