Play Back Machine Data

You can play video of where a machine (such as a compactor, dozer, or excavator running Trimble Earthworks or Groundworks) worked on-site over a time period to see which of that machine’s data is valid for processing in WorksOS.

Play back a short period of automatically imported machine data (TAG files) for a single, specific machine to see where it worked and other information (such as whether the data is valid or invalid for use) about the data being consumed in WorksOS.

Note: Machine playback does not work with manually imported tag files.

Data color-coding

  • Red - invalid; processed TAG files did not meet WorksOS requirements (BLADE_ON_GROUND flag was OFF on the machine)

  • Orange - invalid; process TAG Files did not meet WorksOS requirements (VALID_POSTION was FALSE on the machine)

  • Green - valid; processed TAG files meet WorksOS requirements

Each line in the data indicates the extent (e.g., line is drawn between the left and right ends) of the primary instrument, such as an excavator’s bucket, compactor’s drum, or dozer’s blade. These measurements are accurate to mm. The data does not indicate any part of the machine beyond the primary implement. Each line represents an epoch.

Gaps in the data might mean that:

  • A drum/blade/bucket was not being recorded because monitoring/reporting or mapping was turned off.

  • A compactor drum was ‘decoupled’ due to bouncing on rough ground.

Both valid and invalid data are shown during playback to help you understand and potentially troubleshoot data collection (e.g., blade-on-ground settings are wrong).

Play back machine data

  1. Open the Map View in WorksOS.

  2. Identify the machine data you want to evaluate by clicking the DDV icon and reviewing the machine and date range you want to playback.

  3. On the right side of the Map View, click the Machine Playback Map icon.

  4. On the new Machine Playback screen, select the Machine from those that contributed data to the project, and specify the Start and End times for the playback; the default and maximum duration is an 8-hour period.

  5. Click Load Data. WorksOS searches for all of the TAG files that make up the data for the specified machine and date range.

  6. Once data loads (see the status message at the bottom left of the screen), confirm the device, machine name, and type in the left pane.

  7. Click the Play icon at the bottom of the view. The map will zoom to the work area included in the playback.

  8. During playback, watch both the graphical path of the machine in the view, and the elevation, GPS accuracy, and other properties in the left pane. The values in the left pane update throughout the playback.

  9. You can change the playback speed (1, 2, 4, 8, up to 16x) by clicking the Fast Forward icon at the bottom of the screen. The playback speed is not real-time, but rather the number of epochs displayed at once. You cannot currently drag the playback head back and forth.

Note: Machines record elevation (left and right epochs) up to 5 times per second. Speeding up the playback will show less data granularity as a result.

  1. Select a different machine or time frame to play back data for those.

  2. Click the Back button on the left side of the screen to return to the Map View.

Note: There is currently no way to correct bad field data in WorksOS; you can only identify it in order to make changes on the machine in the field.
