# 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:

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
STEQ | Station equation
