# To stake out positions relative to a GENIO road

1. Start the survey and select the road to stake out.

   If nothing is selected in the plan view, then by default you are ready to measure your position relative to the GENIO road.

2. To stake points offset from the road, leaving the roadway clear for construction, define a construction offset.

3. To view the perpendicular cut/fill to the road, select Options and in the Road group box set the Design cut/fill field to Perpendicular.

4. Tap Start.

   The Road navigation screen appears. Tap Options to configure preferences for the navigation display, grade, as-staked point details, or to view stakeout deltas relative to a digital terrain model (DTM).

5. Use the information in the Road navigation screen to see your position relative to the road and navigate to the point to stake it out.

   If your current position is:

   - Within 30 m of the alignment, the plan view shows a dashed green line drawn at a right angle from your current position to the string.
   - More than 30 meters from the alignment, the software navigates you to a position on the alignment. This is calculated by projecting your current position at right angles to the alignment.

6. 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.

   Tap Store.

   The software returns to the navigation screen.

7. Continue measuring points along the road.
8. To exit this stakeout method, tap Esc.

- To understand how your position is calculated between strings, see String interpolation.
- If the road consists of only an alignment (6D string), the V.Dist value will report the vertical distance to this string.
