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.
6HWWLQJV : located at the top of the screen, is a
shortcut to the Surveying Settings screen (Page
R-32).
Foresight : is the point name that will be used
when storing the new point.
$LP &HQWHU : will record the horizontal angle
from the total station, which should be facing the center of the new
point.
6KRRW 3ULVP : will take a shot to the prism, which is located at the
side of the new point.
%DFNVLJKW« : accesses the Backsight Setup screen (Page R-72).
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.
