# To start staking out a GENIO road

When staking out a GENIO road, you can work from the map or from the menu.

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.

From the map

1. In the map, tap the road.

   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.

   Instead of selecting a defined road you can define it now when you need it ("on the fly"). See To define a GENIO road.

2. Tap Stakeout.

   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. Enable the Cut/Fill to surface switch.
   1. In the Surface field, select the surface file from the current project folder.

   2. If required, in the Offset to surface field, specify an offset to the surface. Tap to select whether the offset is to be applied vertical or perpendicular to the surface.

   3. To show the distance to the surface in the stakeout navigation screen, tap Options. In the Deltas group box, tap Edit and select the V. Dist surface or the Perp. Dist to surface delta. Tap Accept.

5. Tap Options to configure preferences for Grade, As-staked point details, Display and Available stations.

6. Tap Next.

   The plan view of the road appears.

7. Select the item to stake out. For the next steps, refer to the topic for the appropriate stakeout method.

   Once the position has been measured and stored, the software returns to either the navigation screen where you can select the next point on the road/string, or to the plan screen where you can select a different stakeout method.

From the menu

1. Tap and select Stakeout.
2. Tap Stakeout roads.
3. If you have not yet started a survey, the software prompts you through the steps to start the survey.

4. In the Select file screen, select the GENIO file. The file must be in the current project folder.

   To configure the software to display the road selection screen instead of the map when you measure and store a position, tap Options and select the Display the road selection screen on escape check box.

5. Tap Next.

6. Select the road to stake out. Tap Next.
7. Enter a value in the Antenna height or Target height field and make sure that the Measured to field is set correctly.
8. Enable the Cut/Fill to surface switch.
   1. In the Surface field, select the surface file from the current project folder.

   2. If required, in the Offset to surface field, specify an offset to the surface. Tap to select whether the offset is to be applied vertical or perpendicular to the surface.

   3. To show the distance to the surface in the stakeout navigation screen, tap Options. In the Deltas group box, tap Edit and select the V. Dist surface or the Perp. Dist to surface delta. Tap Accept.

9. Tap Options to configure preferences for Grade, As-staked point details, Display and Available stations.

10. Tap Next.

    The plan view of the road appears.

11. Select the item to stake out. For the next steps, refer to the topic for the appropriate stakeout method.

    Once the position has been measured and stored, the software returns to either the navigation screen where you can continue measuring points on the road/string, or to the plan screen where you can select the next position to stake or select a different stakeout method.
