Example for a data block for a vertical alignment point:
11...+KILOMETR 71...+0NEXTGEO 72...+0NEXTRAD 83..10+00000000
WI 11 Station (chainage) of a vertical alignment point
WI 71 Type of the following geometric element
WI 72 Radius of the following geometric element or parabola parameter
WI 83 Elevation of the point
Comments:
• The header consists of a single
block.
• Tangents and the EOP contain
“00000NON” in WI72
• Data units and decimal places in
WI’s 11 and 72 are defined by
WI83.
• Tangent and arc lengths are
calculated from the stationing.
• The stationing is projected onto a
horizontal plane.
• If the curve radius point lies above
the centerline, the radius is
positive.
• If the curve radius lies beneath the
centerline, the radius is negative.
• An alignment file must contain at
least two elements.
