Offset Staking - Screen 3
The third Offset Staking screen is used to select the station and section of the road to be staked and to specify an offset
distance from the design point.
Station to Stake: is the station to be staked.
Station Interval: specifies how far to advance from the current station to the next station.
[Next Sta]: advances the current station by the Station Interval.
Note: When advancing, if you want to also stake the locations where the alignment of the road changes, be sure to
check the Stake “Corners”, Not Just Even Intervals option in the Stakeout Settings card. Tapping the
button will
access the Stakeout Settings .
[<<] / [>>]: These buttons are used to select the section of the road that you want to stake.
Offset: When checked, is the offset distance that will be applied to the selected design point. A positive offset extends
from the design point away from the centerline. A negative offset extends towards the centerline.
Subgrade: When checked, allows you to specify a vertical offset from the actual node locations. Positive values result
in the stake location occurring below the selected node. Negative values result in the stake location occurring above
the selected node.
X-Slope (%): is the slope of the selected road section.
1/2 Road Width: displays the width of the selected road section defined in the previous screen. This value can quickly
be edited from this field.
HR: is the rod height.
[Backsight…]: opens the Station Setup screen.
[< Back]: returns to the previous screen .
[Solve >]: opens the next screen .
Offset Staking - Screen 4
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 Instrument to Design Point: displays the angle and distance information from the total station to the design
point (plus offset if specified).
