# To start an integrated survey using a station elevation setup

The station elevation setup for an integrated survey is available only when starting a survey in the Roads software. For other station setup types, refer to the Conventional survey setup section of the Trimble Access Help.

1. From Roads, select Survey / <integrated style name> / Station elevation.

2. Set the corrections associated with the instrument.

   If the Corrections form does not appear, tap Options from the Station setup screen to set the corrections. To make the Corrections form appear on startup, select the Show corrections on startup option.

3. Tap Accept.
4. If required, enter the Instrument point name, Code, and Instrument height. If you are set up in an arbitrary location, accept the default point name and 0.000 instrument height.
5. Tap Accept.

6. Enter the point name, code, and target details for the point with the known elevation. Tap Measure. Once the measurement is stored, the Point residuals appear.

   You can use the pop‑up arrow to select a point from a list, or key in a point. The point needs only a name and an elevation – horizontal coordinates are not required.

7. From the Point residuals screen, tap one of the following softkeys:

- + Point, to observe additional known points
- Details, to view or edit point details
- Use, to enable or disable a point

8. To view the station elevation result, tap Results in the Point residuals screen. To accept the result, tap Store.

   The RTK survey starts. Once the RTK survey has initialized, you can begin to stake out using Precise elevation.

During a precise elevation road stakeout survey, the horizontal navigation is provided by the RTK survey, and the elevation is provided by the robotic survey. When a measurement is initiated, both a GNSS measurement and a conventional measurement are started at the same time. Separate GNSS and conventional measurements are stored in the job database, along with a grid coordinate that combines the results.

If the robotic total station cannot measure to the target, the cut\fill and vertical distance values appear as "?".
