Offset Staking – Screen Four

The fourth Offset Staking screen displays the information needed to
aim the total station toward the selected design point.

Station

: displays the current station and section of the

roadway being staked and the current line segment type
from the polyline that describes the centerline. If
staking the center and an offset was specified,

(To L)

or

(To R)

is also displayed to indicate if the offset is to the

left or right of the centerline, respectively.

Offset

: displays the offset that is applied to the design

point.

Slope

: displays the slope of the road at the section being

staked.

From Gun to Design Point

: displays the angle and

distance information from the total station to the design
point (plus offset if specified).

&LUFOH =HUR : is used to modify the circle on the total

station so that the angle right reading will be zero when it is facing
the current target, which can sometimes be easier than turning to an
obscure angle value. When this button is tapped, the following
actions will occur:

1.

A new backsight circle value is computed, sent to the instrument
and stored in the raw data

2.

The

Angle Right

value is changed to zero to reflect the change. The

instrument now needs to be turned horizontally to zero to face the
current target location.

3.

To prevent errors if this button is used, the backsight set up is
invalidated when exiting the Stakeout dialog. A circle zeroed on a
design point is meaningless once the design point has been
staked.
