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 A1 of spiral (negative

 

 

parameter = spiral into left-hand

 

 

curve)

End of project (EOP) chainage and coordinates of end-point

1A² = L x R where L = length of spiral; R = radius of curve
