50.6.5
Orientate to line
This method can be used to calculate the 2D or 3D local coordinates for the
instrument setup and the orientation of the horizontal circle. The calculation is
done using the distance and angle measurements to two target points.
The first target point defines the origin of the local coordinate system. The first
target point can be measured or selected from the job.
The line between the first and the second target point defines, depending on
the working style, the local direction of North, East or a User defined direction.
The coordinates of the first target point can be changed in the
Measure Tar-
get
screen. Editing the coordinates shifts the origin of the coordinate system.
All coordinates calculated are local coordinates.

Orientate to object
This method is used to set up the instrument referring to an arbitrary object
coordinate system.
The object coordinate system is defined by at least three known points having
3D coordinates. The station coordinates are unknown. To set up the instru-
ment, distance and angle measurements to at least three known 3D target
points must be performed.
After a successful setup, the station coordinates and all subsequently meas-
ured points are referring to the object coordinate system.
The position values Easting and Northing are related to the X/Y plane of the
object coordinate system. The height component refers to the Z-axis.
☞
In contrast to the coordinates, the observation values do not have to
refer to the object coordinate system, as the Z-axis does not have to
be parallel to the plumb line.
☞
Reflector heights always refer to the plumb line. Since the plumb line
does not have to coincide with the Z-axis, changing the reflector
height can lead to changes in all three coordinate components (E, N,
H).
