# Staking out a LandXML road

Do not change the coordinate system or calibration after you have staked out points, or computed offset or intersection points. If you do, the previously staked out or computed points will be inconsistent with the new coordinate system and any points computed or staked out after the change.

To stake a LandXML cross section road it must first be defined and then stored as an RXL file in Trimble Access Roads. To stake it out, simply select the new RXL road to stake. The original LandXML file remains in the project folder but is no longer used. For more information, see To define a LandXML cross section road and Staking out an RXL road.

To stake a LandXML string road:

1. In the map, tap the road and then tap Stakeout. Alternatively, tap and select Stakeout, tap Stakeout roads and select the road to stake then tap Next.

   Use the Filter alignments by name match field to help you select the alignment to stake. This option is only available when selecting the road to stake from the menu.

   If the road you want to stake out is not shown in the map, tap in the map toolbar to open the Layer manager and select the Map files tab. Select the file and then make the appropriate layer(s) visible and selectable. The file must be in the current project folder.

2. If you have not yet started a survey, the software prompts you through the steps to start the survey.

3. Enter a value in the Antenna height or Target height field and make sure that the Measured to field is set correctly.

4. Enter the Station interval for lines and Station interval for arcs and transitions or accept the default value set when the alignment was defined.

   Station interval values are required when staking out a station on a string. These values are optional for other survey methods.

5. Tap Options to:
   - Configure preferences for Grade, As-staked point details, and Display.
   - Enable staking out relative to a digital terrain model (DTM).

6. Tap Next.

   The road is ready to stake, using your preferred stakeout method. For more information, refer to the topic for the selected method. See:

- If a road consists of a horizontal alignment only, you can stake it out in only two dimensions.
- The horizontal and vertical alignments of a road may not start and end at the same station values. When they start and end at different station values, you can only stake out points in three dimensions if their stations lie within the horizontal alignment.
