Slope Staking
6WDNHRXW 6ORSH 6WDNLQJ
The Slope Staking screen is used to locate the catch points for a
roadway in any terrain.
The first screen is used to define or select the line
that describes the centerline of the road to be
slope staked. An existing polyline or alignment
can be selected, or a series of existing points can
be entered to define the centerline.
7DS /LQH« : allows you to tap an existing
polyline or alignment that defines the centerline
of the road.
7R)URP« : allows you to enter a range of points
to define the centerline of the road.
Begin Station : defines the station at the beginning of the centerline.
%DFNVLJKW« : accesses the Backsight Setup screen.
1H[W! : opens the next screen.
Slope Staking – Screen Two
The second screen is used to describe the profile
of the road.
1/2 Road Width : is the horizontal width of L eft
and R ight sides of the road, respectively, from the
centerline to the nearest edge of the curb or
ditch.
X-Slope : is the cross slope of the L eft and R ight
sides of the road, respectively. The slope is
computed from (

⋅ ). (A negative slope will
cause water to run from the centerline toward the edge.)
