[Next Station]: advances the current station by the Station Interval.
Note: If the Stake Corners option is selected in the Stakeout Settings screen, the [Next Station] button will also stop at
any horizontal or vertical alignment node, and the beginning and end of any widening and super elevation that falls
within the interval.
[Backsight…]: Opens the
screen.
H. Map Card
The H. Map card displays information about the horizontal details of the road at the current station.
Segment Type: displays the type of horizontal section at the current station.
Left / Right: is the description of the left and right templates that are being used at the current station.
V. Map Card
The V. Map card displays a graphic of the cross-sectional profile of the road at the current station. The hinge points
and slopes are also displayed.
Slopes Card
The Slopes card is used to specify the cut and fill slopes that will be used when computing the location of the catch
point. The default values are the slopes stored in the template for the section being staked. To override a default slope,
check the appropriate box and key in the new slope. The new slope entered will always be used regardless of the
values stored in the templates. Changes to slopes will be reflected in the V. Map card graphic.
Cut Slope: is the left and right slope, respectively, used when the terrain requires a cut (the hinge point is located
below the terrain’s surface).
Fill Slope: is the left and right slope, respectively, used when the terrain requires a fill (the hinge point is located
above the terrain’s surface).
Cut/Fill Hinge Points Cards: The Fill Hinge Points tab and the Cut Hinge Points tab are used to select the segment
where you want the hinge point location to be computed from in situations requiring a fill or a cut respectively. (The
hinge point will occur at the node of the selected segment furthest from the centerline.) The hinge point can also be
defined at different segments for the left and right sides of the road.
Left / Right: is the specified left and right segment, respectively, to compute the hinge point from in a situation that
requires a fill. Changes to these fields will be reflected in the V. Map card graphic.
[Stake CP >]: opens the next slope staking screen. The following slope staking screens are identical to non-road
layout slope staking screens and are described starting
.
Road Station and Offset
[Roads] [Show Station]
The Road Station and Offset routine allows you to take a shot to a prism that is positioned anywhere on the road and
compute the details of where that point is located in relation to the road. This information can then be compared to the
