The five identifiers ALN, PRF, CRS, STA and EQN identify the type of file and must be used when creating the data files. The ? can be any valid DOS character. The file extension GSI defines the file as a GSI file and must be used.

1. Permitted elements in the Hz-alignment

Straight

defined by chainage and

 

 

coordinates of starting 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)

Compound curve defined by chainage and coordinates of starting point Radius of arc (R1, R2)

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

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