Manual Flight Lines

The Manual Flight Lines tool, found on the Sensor tab of the ribbon, is used in conjunction with the Auto Create Flight Lines tool , also found on the Sensor tab of the ribbon, as part of the step in the workflow where one takes the real-time trajectory of the flights and segments them into only those sections you need for data generation.

The flight lines are generated from the [XXX]_TrajectoryPoints layer. LP360 will use these points to create vectors representing the flight lines and add them to a layer called [XXX]_FlightLines.

How to manually create flight lines

1. Flight lines may be added manually by selecting trajectory points (red points) at the beginning and end of the desired line.
   1. Select the Select/Edit Features tool on the Feature Edit tab.
   2. Select a trajectory point at the beginning of the desired flight line. The point will be highlighted when selected.
   3. Hold CTRL, then select a trajectory point at the end of the flight line. Ensure it is on the same TrajectoryPoints layer. Both trajectory points should now be highlighted (Figure 1).

Figure 1 – Manually Creating Flight Lines

2. Select Manual Flight Lines to create flight lines from the selected trajectory points.
3. A new flight line feature is created on the FlightLines layer of the Cycle corresponding to the selected Trajectory Points.
4. If the Auto Create Flight Lines dialog is not open, be sure to Save Feature Edits on the Feature Edit tab to save the edits.

Note: If you select Trajectory Point patterns that do not form the required base for creating a flight line, you will receive an error message that explains the issue such as shown in Figure 2, "LP360 Error: Error with the selected Trajectory Points: There was a single selected 'start' point without a corresponding single 'end' point. A group of contiguous selected points were found instead.

The flight lines are stored as a feature file (.SHP) for each each Cycle in the Project\Area\Cycle\Flight\Positions subfolder of your project.
