The program reads the geometrical elements of an
alignment from files expressed in GSI format. The data
for the alignment are grouped in accordance with the
three components of an alignment. The file names must
comply with certain rules:
1. Hz-alignment
File name: ALN?????.GSI
2. V-alignment
File name: PRF?????.GSI
3. Cross section
File name: CRS?????.GSI
You can insert a permitted character for a DOS file
name in place of a ? .
1. Permitted elements in the Hz-alignment
• Straight defined by chainage and
coordinates of tarting point
• Curve defined by chainage and
coordinates of starting point
Radius of arc (- = left-hand curve
+ = right-hand curve)
• Spiral defined by
chainage and coordinates of
starting point
parameter A
1
of spiral (negative
parameter = spiral into left-hand
curve)
• End of project (EOP) chainage and coordinates of
end-point
1
A² = L x R where L = length of spiral; R = radius of
curve
