Stakeout navigation display

The information shown when navigating to points during stakeout depends on whether you are performing a Conventional or GNSS survey, and the options you have configured in the Stakeout options screen.

To configure these options:

  • In the survey style, tap and select Settings / Survey styles / <Style name> / Stakeout.

  • During stakeout, tap Options in the stakeout navigation screen.

Use the Display group to configure the appearance of the navigation display during stakeout:

  • To show the large navigation arrow in the navigation screen, set the Show stakeout graphics switch to Yes.

    If you are using a controller with a smaller screen, or you want to fit more navigation deltas on the screen, set the Show stakeout graphics switch to No. The other fields in the Display group are hidden when the switch is set to No.

  • Select the Display mode: The options are:

    • Direction and distance – the stakeout navigation display shows a large arrow pointing in the direction you have to move. When you are close to the point, the arrow changes to the in/out and left/right directions, relative to the instrument.

    • In/out and left/right – the stakeout navigation display shows in/out and left/right directions.

    By default the software automatically gives in/out and left/right directions from the Target perspective in a robotic survey, and from the Instrument perspective when connected to a servo instrument using a face plate or cable. To change this, change the settings in the Servo/Robotic group box. For more information, see Servo/Robotic.

  • Use the Distance tolerance field to specify the allowable error in distance. If the target is within this distance from the point, the software indicates that the distance is correct.
  • Use the Angle tolerance field to specify the allowable error in angle. If the conventional instrument is turned away from the point by less than this angle, the software indicates that the angle is correct.

  • Use the Grade field to display the grade of a slope as an angle, percent, or ratio. The ratio can be displayed as Rise:Run or Run:Rise. See Grade.

In the Deltas group, review the deltas shown for the current stakeout item. To change the deltas shown, tap Edit.

Deltas are the information fields shown during navigation that indicate the direction and distance you need to travel to the item you want to stake out. See Stakeout navigation deltas.

To display the cut or fill relative to a surface during stakeout, enable the Cut/Fill to surface switch. In the Surface field, select the surface file from the current project folder.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.

If your Spectra Geospatial controller includes an internal compass, you can use it when staking out a position or navigating to a point. To use the internal compass, select the Compass check box. Spectra Geospatial recommends you disable the compass when you are near magnetic fields that may cause interference.

Use the Display group to configure the appearance of the navigation display during stakeout:

  • To show the large navigation arrow in the navigation screen, set the Show stakeout graphics switch to Yes.

    If you are using a controller with a smaller screen, or you want to fit more navigation deltas on the screen, set the Show stakeout graphics switch to No. The other fields in the Display group are hidden when the switch is set to No.

  • Select the Display mode: The options are:
    • Target centered – the selected point stays fixed in the center of the screen
    • Surveyor centered – your position stays fixed in the center of the screen
  • Choose a setting in the Display orientation field. The options are:
    • Direction of travel – the screen will orientate so that the top of the screen points in the direction of travel.
    • North / Sun – the small orientation arrow shows the location of North or the sun. The screen will orientate so that the top of the screen points toward North or the sun. When using the display, tap the North/Sun softkey to toggle the orientation between north and the sun.
    • Reference azimuth:
      • For a point the screen will orientate to the Reference azimuth for the job. The Stake option must be set to Relative to azimuth.
      • For a line or road the screen will orientate to the azimuth of the line or road.

    If, when staking a point, the Display orientation is set to Reference azimuth and the Stake option is not set to Relative to azimuth the display orientation behavior will default to Direction of travel. For Stake options, see GNSS stake methods.

  • Use the Grade field to display the grade of a slope as an angle, percent, or ratio. The ratio can be displayed as Rise:Run or Run:Rise. See Grade.

If you are using IMU tilt compensation and the IMU is aligned, the heading from the receiver is always used to orient the GNSS cursor, the large stakeout navigation arrow and the close up screen. You must be facing the LED panel of the receiver for these to be orientated correctly.

By default the software displays navigation information to the point from your current position. To navigate using a cross‑track line between the point to be staked out and a reference point, change the Stake method. See GNSS stake methods.
