Stations available for stakeout

You can customize the stations available for stakeout when using the following methods:

Station on string (from a road design file or from strings and surfaces)
Skew offset (from a road design file)

To customize the stations available, select the stakeout method and then tap next to the Station field in the Stakeout screen. The Select station screen appears, listing the stations on the centerline.

Station interval settings

If required, edit the Station interval for lines and Station interval for arcs and transitions or accept the default value set when the road was defined. A separate station interval value for arcs and transitions enables you to tighten the interval for curves and more accurately represent the design on the ground.

Select the station interval Method:

The 0 based method is the default method and gives station values that are multiples of the station interval. For example, if the start station is 2.50 and the station interval is 10.00, the 0 based method produces stations at 2.50, 10.00, 20.00, 30.00 and so on.
The Relative method gives station values relative to the start station. For example, if the start station is 2.50 and the station interval is 10.00, the Relative method produces stations at 2.50, 12.50, 22.50, 32.50, and so on.

If you have configured different values for the Station interval for lines and the Station interval for arcs and transitions, then the list of available stations may include stations at different intervals.

In the Auto increment field:

Select Sta+ to automate the selection of the next station for stakeout.
Select Sta- to automate the selection of the previous station for stakeout.
Select No if you want to manually select the next station to stake.

Selecting Sta+ or Sta- in the Auto incrementfield provides a faster, more streamlined workflow.

Station interval settings (including Method and Auto increment settings) configured in the Select station screen are written to the road file so that the same settings are used if the file is shared with other survey crews. If the file is an IFC file, the Station interval settings are written to a Trimble Additional Properties (TAP) file. The TAP file is stored in the same folder as the IFC file of the same name. If other survey crews are using the IFC file, then you must share the .tap file with the .ifc file to ensure all survey crews use the same settings.

Available stations

To configure the types of stations shown in the station list, select the appropriate Available Stations check boxes.

Depending on the road type, you can select the following:

Computed Sections defined by the station interval
Horizontal Curve (key stations defined by the horizontal alignment)
Vertical Curve (key stations defined by the vertical alignment)
Template (stations where templates have been assigned)
Super/Widen (stations where superelevation and widening has been assigned)

The station abbreviations used in the Roads software are:

Start/end	E	End station
Computed sections	CXS	Computed sections defined by the station interval
Vertical curve	VCS	Vertical curve start
	VCE	Vertical curve end
	VPI	Vertical point of intersection
	Hi	Vertical curve high point
	Lo	Vertical curve low point
Superelevation/Widening	SES	Superelevation start
	SEM	Superelevation maximum
	SEE	Superelevation end
	WS	Widening start
	WM	Widening maximum
	WE	Widening end
Horizontal curve	PI	Point of intersection
	PT	Point of tangent (Curve to tangent)
	PC	Point of curvature (Tangent to curve)
	TS	Tangent to transition
	ST	Transition to tangent
	SS	Transition to transition
	CS	Curve to transition
	SC	Transition to curve
Template assignment	T	Template assignment
Other	DXS	Design sections defined by the positions in the file
Other	STEQ	Station equation
