Centerline

The offset value needs to be set to a -0.600 m. The negative value is used because the point to stake is left of centerline.

To accept the value press .

The final step in the process is to select the method to use for computing the elevation of the offset point to be staked. The "ROADPLUS" program provides three methods to choose from:

Horizontal

- The elevation is computed

 

horizontally to the catch point.

Previous Element

- The elevation is computed on an

 

extension of the grade of the

 

previous element.

Interpolated

- The elevation is interpolated to

 

intersect the design slope of the

 

cross section.

The following illustration shows the three vertical options for stake offset.
