# Stations available for stakeout

You can customize the stations available for stakeout when staking a:

- Station on a line, arc, polyline, or alignment

- Station/offset from a line, arc, or polyline

- Side slope from a polyline or alignment

- Skew offset

To customize the stations available, select the stakeout method and then tap next to the Station field in the Stakeout screen.

## Station interval settings

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.

When staking an alignment, you can edit the Station interval for lines and Station interval for arcs and transitions or accept the default value set when the alignment 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.

When staking an alignment, 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.

When staking stations on an alignment, Station interval settings (including Method and Auto increment settings) configured in the Select station screen are written to the alignment file (for example, the RXL 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.
