This tool was deprecated in v2025.1 as it was merged into the improved Geocode LiDAR and new Sensor Processing Launcher tools. The tool has been moved to the Legacy Tab.

Requires an LP360 Drone or LP360 Land Standard license.

After Creating Flight Lines using Trajectory Processing , the next step is to run Create TrueView Trajectories to generate a trajectory for each flight line, drive pass, or walking path using the flight lines layer and the refined post-processed trajectory. Optionally and recommended, you may also update the image EXIF tags at the same time.

These fields of this dialog are usually auto populated if the post process trajectory solution was successful.

Flight Line Layer - Select the flight line layer from which to generate TrueView trajectories if multiple Cycles are being processed.

Calibration file – The TrueView sensor calibration is critical to get accurate LiDAR and imagery data for all supported system types. Select the option for the calibration file you wish to use:

• Use Latest Available Calibration File on TrueView Reckon (Recommended) – The latest calibration file for each sensor is stored on TrueView Reckon, the sensor management backend. When this option is selected, LP360 Drone will use the latest calibration file found on TrueView Reckon to process the data. This is the recommended option as some smarts exist on Reckon and in LP360 Drone to help ensure the correct calibration file for the system and Cycle. If your system does not have a calibration file on Reckon, please contact support@geocue.com for assistance.
• Diagnostic Only: Users should never normally use either of these options, except for: DJI Zenmuse L1/L2 processing, where it should not be modified from the default; Imagery only sensors, such as the P4RTK or P1, where the user does not have a camera calibration on Reckon and is therefore following a more arduous workflow involving measuring control rather than a more automated Ortho Mapping processing with only check points for validation (Image Explorer will also not be usable without a camera calibration). Otherwise, if the “Latest Calibration” option above is greyed out, please contact support@geocue.com for further assistance. for further assistance.
  1. Use Cycle-resident Calibration File – If this option is selected, the calibration file in the system folder of Cycle being processed will be used to process the data. This may not be the latest calibration file if updates to your calibration have been made and those updates were not copied to the USB prior to acquisition.
  2. Manually Select Calibration File – This choice will invoke a dialog that allows you to select a file from all available calibration files for this sensor from Reckon. If you select this choice, the Calibration File Picker dialog (Figure 2) will be displayed when you press the Create Trajectories button at the bottom of the Create TrueView Trajectories dialog. You can pick the calibration file you desire using the dropdown picker.

Retained Photos Layer Settings – Allows the user to specify the photos to be kept for downstream processing. The notion of “Retained Photos” creates a layer of the retained photos on a new layer called “RetainedPhotos.” See Retained Photos Layer Settings for details on the available options.

Target Epoch – Deprecated in 2024.2 as now handled by the Project Epoch. In prior versions, select Cycle Date for coordinate reference systems using the WGS84 datum, otherwise select Custom Date and enter the applicable epoch for the datum of your coordinate reference system. For example, NAD83(2011) has an epoch date of 2010.0. Typically, the epoch date for your project datum should be selected by default. You will be prompted after selecting OK if the project epoch differs from the value entered on this dialog. The project epoch is set when the project CRS is selected but can be modified in File -> Project Settings -> Project -> Project Epoch. 

Processing Settings

Update Photo EXIF Tags with True Pose® Information – Performs the operations of the Update EXIF Tags tool. Recommended. 

Starting Flight Line Number (Point Source ID) – When there are multiple Cycles or flights in a project it is important to assign unique point source IDs, or flight line numbers to each line. Selecting a unique starting ID allows the user to determine the best values between 1 and 65535 to use for each line. For multi-Cycle projects it is suggested to use a nomenclature, such as CCCFF, where CCC is the Cycles flown for the project, 1-645, and FF is the flight line per Cycle, 1-99, to keep the point source IDs unique within the project.

How to Create Trajectories

1. Select the Create Trajectories button.

Figure 5: Older Create TrueView Trajectories dialog showing the Target Epoch selection

2. Verify the Flight Line Layer is correct; typically, there will only be one such layer on the project.
3. Select Calibration File.
4. Select option for which photos will be retained within the flight lines.
5. Select the check box if you wish to Update EXIF Tags during the create trajectories process.
6. Select Create Trajectories .
7. TrueView trajectories are created for the selected Flight Line layer. Once trajectories for a flight line are created the flight line will change from blue to magenta. Close the dialog when finished.

Tips

If you cannot remember if you have run the Create TV Trajectories step, there is no harm in running it multiple times. The FlightLines layer symbology turns magenta when this step has been run. If you want to confirm creation of the flight line trajectories, you can inspect the Flight Line attributes using the LP360 Feature Analyst tool. Right-click the Flight Line layer in the TOC and then left-click “Feature Analyst …” (see Figure 81).

Figure 3 - Opening Feature Analyst on the Flight Line layer

Observe the “TVTrajFIle” column in the Feature table of Feature Analyst (Figure 4). If this column is blank, flight line trajectories have not yet been created. Figure 4 shows the feature table after creation of the TrueView Flight Line trajectories. Note a file location is now populated in the TVTrajFile attribute column.

Note: The Flight Line Trajectory files created in LP360 Drone for 3D Imaging Sensors (3DIS®) are in the Terrasolid trajectory format. These trajectories can be directly used in products such as TerraScan, TerraMatch and TerraPhoto.
