Hi everybody,
eurospeleo meeting in Austria starts tomorrow. Me and Martin (Budaj), we
are leaving there tomorrow and we will be there until Surveying workshop on
Sunday afternoon. If you are interested, we could meet at welcome ceremony.

The altitude needs indeed to be given, but you should also specify that
it is highly unreliable by giving it a every high standard deviation, like:
fix MyRadioLocation accurate_x_coord accurate_y_coord
approximate_altitude 3 3 1000 # stddev of 3m in x and y and 1000m in z
This should guaranty
Add label altitude to that station and use it.

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
accumula
Assuming that you've got another fix for the entrance then you should be able
to get the height for the end station. Just look at the .3d file. That will
give you the relative altitude at the end - just use that.

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 position which is about 150m beyond the estimated location we
get from surveying. So now I wanted to use this position to
