To measure continuous topo points

Use the Continuous topo measurement method to measure points continuously, for example a line of points at a fixed interval.

You can also use the Continuous topo measurement method to store depths measured using an echo sounder. For more information, see To store depths using an echo sounder.

To start Continuous topo measurements:

  1. Tap and select Measure / Continuous topo.

  2. Enter the Start point name. The point name increments automatically.

  3. If required, enter a value in the Target height field.
  4. Select the method using the steps below.

  1. Select the Method.

    A point is stored when one of these predefined events occurs:

    • the time interval has elapsed (Fixed time method)
    • the distance has been exceeded (Fixed distance method)
    • the time interval has elapsed and/or the distance has been exceeded (Time and distance or Time or distance method)

    For a postprocessed survey, you must use the Fixed time continuous method. By default the time interval is set to the same value as the logging interval configured in the Rover options screen of the postprocessed survey style.

  2. Enter a value in the Distance field and/or the Time interval field, depending on which method you are using.
  3. Tap Start. Data starts recording.

  4. Move along the feature to be surveyed.

    To store a position before the predefined conditions have been met, tap Store.

  5. To stop measuring continuous points, tap End.

  1. In the Method field, select Stop and go.

  2. In the Stop time field, enter the period of time the target must be stationary before the instrument starts to measure the point.

    The target is deemed to be stationary when its velocity is less than 5 cm/sec.

  3. Enter a value in the Distance field for the minimum distance between points.
  4. Tap Start. Data starts recording.

  5. Move along the feature to be surveyed. A point is stored when the stop time and distance settings have been met.

    To store a position before the predefined conditions have been met, tap Store.

  6. To stop measuring continuous points, tap End.

If you are using a Trimble total station continuous topo uses only synchronous angles and distances. If the instrument:

  • Has a tracklight that has been enabled, the tracklight is disabled for 2 seconds when the measured point has been stored.
  • Is a FOCUS 30/35 instrument with laser blinking enabled, laser blinking is temporarily disabled when using Continuous topo.

If you are using a FOCUS 30/35 instrument with laser blinking enabled, laser blinking is temporarily disabled when using Continuous topo.
