# Create a Cloud ## Summary Once a post processed trajectory has been created, the next step is to split up the trajectory into "intervals" or flightlines/drivelines. Intervals need to be created to isolate the desired flightlines prior to fusing a point cloud. By removing turns in the data, less accurate areas of the trajectory are excluded to ensure most accurate point cloud possible for a given acquisition. ## Details There are two types of Intervals you can create: 1. [Automatic Intervals](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/create-a-cloud/automatic-intervals) 2. [Manually Split Intervals](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/create-a-cloud/manually-split-intervals) Once intervals have been created, LiDAR sensor parameters need to be reviewed and adjusted to adhere to the project planning and data needs. After the intervals and sensor parameters have been adjusted to the users' specifications, a cloud can be created. ### --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
