Template: displays the name of the template that is used at the rod position.

Segment: displays the name of the template's segment at the rod position.

Elev: displays the elevation at the rod position.

Offset Dist: displays the perpendicular offset from the centerline to the rod position.

Right of Line / Left of Line / On Line: displays if the rod position is to the right of the centerline, left of the
centerline, or on the centerline, respectively.

Cross-Section Card

Station: displays the station at the rod position.

Template: displays the name of the template that is used at the rod position.

Segment: displays the name of the template's segment at the rod position.

Cut / Fill: is the necessary cut or fill that will bring the rod position even with the road's surface.

Cut / Fill to CL: is the necessary cut or fill that will bring the rod position to the same elevation as the centerline at
the current station.

Cut / Fill to Edge: is the necessary cut or fill that will bring the rod position to the same elevation as the outer edge of
the last segment at the current station.

Shot Data Card: Displays the angles and distance measured by the total station from the last shot.

or [Roads] [Show Station] [Equation Settings]

The Station Equation screen is used to configure the stationing for an alignment with stationing that changes at a
specific location. This situation might occur where the road you are staking merges with another road and once you
stake past the point where the roads merge, you want to use the stationing assigned to the other road.

Once you pass the location where the stationing changes, all ahead stations are displayed with a (2) after it to
differentiate between a back and ahead station, such as 11+00 (2). Likewise, when keying in an ahead station, you
must append it with a (2) to indicate it is an ahead station.

Road Name: Displays the name of the current alignment.

Back: Defines the stationing on the back alignment where the stationing change occurs.

Ahead: Defines what the new stationing is for the same location defined in the Back field.

Increase: indicates the stationing should increase as you move forward past the location where the stationing changes.

Decrease: indicates the stationing should decrease as you move forward past the location where the stationing
changes.
