Default Batch Processing #

The Batch Processing tool is designed for processing multiple projects simultaneously and can be used for both RTK and PPK datasets.

Detailed Procedure #

  1. Transfer Data:

    • After recording a dataset, remove the USB thumb drive from the payload and plug it into the computer used for data processing.
    • Navigate to the root folder containing the recorded dataset and copy the entire flight folder locally to the computer for faster processing speeds.
      • If a custom project name was set through the “Status” page of the GUI, it will appear as a prefix to the automatically configured flight name stamped with UTC time. The generic naming convention for the dataset is as follows: RESEPI-AAAAAA-BBBB-CC-DD-EE-FF-GG
        • AAAAAA: The device’s internally broadcasted Wi-Fi SSID.
        • BBBB: The year the data recording was initialized.
        • CC: The month the data recording was initialized.
        • DD: The day of the month the data recording was initialized.
        • EE: The hour of the day (based on 24 hours) the data recording was initialized.
        • FF: The minute of the day the data recording was initialized.
        • GG: The second of the day the data recording was initialized.

  2. Activate License:

    • Ensure that your PPK license is activated when performing PPK processing, as shown in Figure 1.
Figure 1. Local License Manager.
  1. Configure Batch Processing:
    • Open PCMasterProGL and navigate to Batch Processing > Configure Batch Processing.
      • Do not close the PCMasterPro window, as it will be used for trajectory selection.
    • Optional: Name the first project by selecting “New Project 1” under the “Project Name” tab, as shown in Figure 2.
    • Select “Click here to select project file” and navigate to the .pcmp file for the desired project.
      • Allow time for unpacking data files after file selection. Progress will be shown in the bottom left corner of the PCMasterPro window.
    • Configure the project:
      • Select “Needs Configuration”.
      • Select the project number on the far left, then select “Configure Selected”.

  1. Project Configuration:
    • In the configuration menu, select the “Select” button next to “Base File:” to choose the base station file, as shown in Figure 3. Navigate to the base station file to be used in processing this dataset.
    • Input the “IMU to GPS Lever Arm” values.
      • These values will be automatically entered according to the preset values within the RESEPI GUI prior to recording and can be adjusted if needed.
    • Enter the Latitude, Longitude, and Ellipsoidal height values for the base station used for recording.
      • These values will be detected by PCMasterPro and generally do not need adjustment unless the base station data was post-processed. Simply checking “Use Default Base Position” will be sufficient for most users.
    • Select the preferred Geoid model for processing the project.
    • Further options include “Convert to LAZ” and “Colorize”:
      • “Convert to LAZ” will compress the final cloud into a smaller file, formatted as “.laz” instead of “.las”.
      • “Colorize” will colorize the point cloud. Uncheck if no colorization is required.
    • Choose to “Select Trajectory” or “Select Entire Trajectory”:
      • “Select Trajectory” allows specific portions of the cloud to be identified for export.
      • “Select Entire Trajectory” will export all points along the entire trajectory with default cloud filters applied (LiDAR field of view and range).
    • Save the project by selecting the “Save Project” button.
    • Add, configure, and remove as many projects as needed:
      • Add another project by selecting “Add Project”.
      • Remove a project by highlighting the project number on the far left and selecting “Remove Selected Projects”.

  1. Settings and Processing:
    • If merging LAS/LAZ clouds from multiple projects into a single file, processing all datasets simultaneously, deleting unnecessary cloud files, or changing the output directory is needed, configure these options within File > Settings in the Batch Processor window.
      • The default output directory for any project is the “clouds” folder within each project folder.
        • The “clouds” folder is only created upon LAS export, so it will not be visible upon unpacking.
  2. Begin Processing:
    • When ready to begin processing, select the “Process” button.
      • “Processing” or “Waiting” will be shown in the “Status” column, as shown in Figure 4. Upon completion, the clouds will be produced in the “clouds” folder unless specified otherwise.
    • A pop-up message will indicate when processing and projection are finished, as shown in Figure 5.
