Field
Description
Ref offset
Horizontal offset from the line of the surface grade used as
reference. Depends on
Ref line
and is identical to
Right off-
set
or
Left offset
.
Ref height
diff
Height difference from the line of the surface grade used as
reference. Depends on
Ref line
and is identical to
Right
height diff
or
Left height diff
.
Surface
grade ratio
Slope ratio of the surface grade.
Square off-
set
Offset from the surface grade, perpendicular to the surface
grade.
Square
slope dist
Slope distance from the slope reference line to the current
position perpendicular to the slope. The slope distance is
always at the same grade as the defined or current slope. If
the current position is above or below the slope, the slope
distance is projected square to the slope. The slope distance
is calculated to the defined reference point.
The
Square slope dist
is measured from the current posi-
tion to the reference line.
CL height
diff
Height difference from the centreline.
CL height
Height of the centreline at the current chainage.
CL radius
Radius of the centreline at the current chainage.
CL type
Element type of the centreline.
CL offset
Perpendicular horizontal offset from the centreline. This field

page.
CL tangent
Tangent direction of the centreline at the current chainage.
Width
Horizontal width of the surface grade.
Nearest hz
tangent
point
The chainage difference between the measured point and
the nearest tangent point of the design is displayed. The
nearest tangent point is the start/end point of a road seg-
ment.
