# Licensing

Certain features in SpatialExplorer require a valid license to run. SpatialExplorer features additional advanced post processing modules such as [LiDARSnap](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/lidar-snap/lidarsnap-v4) (LiDAR calibration), [CameraSnap](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/camera-snap/camerasnap) (camera calibration), and [Automated Classification](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/classification#summary). A full report of licensed features can be found below or on [Our Website](https://www.phoenixlidar.com/software/).
