# Load sensor transform/extrinsics from file

Calibration values that appear in the [**Calibration**](/spatialexplorer-8-and-9/user-interface/windows/project/rover/cameras/camera-calibration-settings.md) tab of the camera settings menu can be imported from a PLP file. This is useful from a customer support context, as Phoenix LiDAR customer support can provide a customer calibration values by sending them a PLP file. Users can also use this feature to apply a calibration to several data sets without manually entering values. 

In most cases, after pointing SpatialExplorer to the PLP, you will select to import the calibration from **Sessions**:

It's also recommended to import the **Sensor->IMU transform**:
