To stake out a line

Before you start, configure your navigation display settings. You can stake relative to a DTM or the design elevation, if required.

1. To select the line:

   • From the map, you can:
     • Select the line and tap Stakeout.
     • Select the two points that define the line, and then tap and hold in the map and select Stake out line.
     • Double‑tap the line in the map.

     When selecting a line to stake out from the map, tap near the end of the line that you want to designate as the start. Arrows are then drawn on the line to indicate the direction. If the direction is incorrect, tap the line to deselect it and then tap it at the correct end to reselect the line in the direction required. Alternatively tap and hold in the map and select Reverse line direction from the menu.

     If the line has been offset, the offset directions are not swapped when the line direction is reversed.

   • From the menu, tap and select Stakeout / Lines. Tap next to the Line name field and select:
     • List to view a list of previously defined lines to select from.
     • Two points to define the line from two points.
     • Azimuth to define the line by a start point and an azimuth.

2. In the Stake field, select the method and then fill out the required fields. Refer to the Line stakeout methods below.

   To select the station to stake, key it in, tap the Sta‑ and Sta+ softkeys, or tap next to the Station fields to select a station from the list. To select the start or end station, tap the Start station or End station softkey.

   To customize the stations available for stakeout, tap next to the Station field to view the Select station screen. See Stations available for stakeout.

   If the station interval value is null, no station labels are displayed. If the station interval is 0, the station labels for the start and end stations plus any PI, PC or PT stations are displayed. If the station interval is a numeric value, labels for all stations are displayed (depending on the zoom scale).

3. To review the line definition, tap Details.
4. Enter the Antenna height or Target height, the value of the station to be staked out (if any), and any further details, such as horizontal and vertical offsets.
5. Tap Start.

6. Navigate to the point.

   When the stake method is Station on line, Station/offset from line or Skew offset, you can edit the elevation. To edit do this, press the Space key or tap and enter the new elevation value. To restore the original elevation after editing, press the Space key or tap and then tap next to the Design elevation field and select Reload original elevation.

7. When the point is within tolerance, tap Measure to measure the point.

   When using a Trimble SX12 scanning total station in TRK mode with the laser pointer enabled, the Stakeout screen shows the Mark point softkey instead of the Measure softkey. Tap Mark point to put the instrument into STD mode. The laser pointer stops flashing and moves to position itself at the EDM location. When you tap Accept to store the point, the instrument automatically returns to TRK mode and the laser pointer resumes flashing. To remeasure and update the stakeout deltas, tap Measure after you tap Mark point and before you tap Accept. For more information, see EDM settings.

8. Tap Accept to store the point.
9. If you selected the View before storage option, the staked deltas you selected in the Stakeout options screen are shown. Tap Store.
10. The software returns to the navigation screen or, if you selected multiple items to stake out, the software returns to the Stake out items list.
