Cut line ends
Not Lite
Cut line ends command removes points from the beginning and end of each trajectory. The routine affects defined time range of points in the trajectory. This may be useful cleaning data with lower quality record in the beginning or end of a line, if the system is less stable or sensor is still warming up.
This tool is dependent on the trajectory data and point cloud time stamps. Use Manage Trajectories to load the trajectory data and split the trajectories into lines before using this tool.
To cut line ends:
1. Select Cut line ends command from the Line pulldown menu.
This opens the Cut Line Ends dialog:
2. Define settings and click OK.
This starts the process.
