The **Compute SOCS** tool is used to recompute the original range and scan angle values associated with each point, which is necessary when optimizing a 3rd party LAZ using **LiDARSnap**. **Compute SOCS** takes the world position and back-calculates the scan angle and scan range using the trajectory and sensor model specified by the user:
