Horizontal Angle Offset
Survey Horizontal Angle Offset.
The Horizontal Angle Offset screen allows you to compute and store
the location of a new point that cannot be occupied, such as at the
center of large tree.
The routine shoots a prism positioned at the
side of the new point and then reads the
horizontal angle when aiming toward the
center of the new point to compute the new
point’s location.
: is a shortcut to the Surveying Settings
screen (Page R-44).
Foresight: is the
point name that will be used
when storing the new point.
Aim Center : will record the horizontal angle
from the total station, which should be facing
the center of the new point.
Shoot Prism : will take a shot to the prism, which is located at the
side of the new point.
Backsight… : opens the Backsight Setup screen (Page R-122).
Note: The new point will have the same elevation as the point
occupied by the prism.
Note: The prism only needs to occupy the location at the side of the
new point. A prism is not necessary when shooting the location
directly in front of the new point.
