Ht Offset
Offset of the reference elevation in
relation to the first base point.
∆ ∆ ∆ ∆ ∆
Ht
Height difference between the target
point and the reference elevation.
Ht Offset
Offset of the reference elevation in
relation to baseline.
For the configuration Elev. Ref. =
Baseline, the reference elevation for
the calculation of
∆
Ht values is the
elevation of the baseline at the
reflector position.
You can modify the reference
elevation by specifiying a height
offset (Ht.Offset) in the dialog for the
definition of the reference line.
Interpolated reference elevation
Illustration: elevation profile
Constant reference elevation
For the configuration Ref.Elev. = 1st
Base Point, the reference elevation
for the calculation of
∆
Height values
is the elevation of the 1st base point.
The ref. elevation can be modified by
specifying a height offset (Ht.Offset)
in the “Define Reference Line” dialog.
With Edit Elev. the height of each
point can be changed separately (see
Config. Dialog).
