# Processing Parameters

Add a set of **Processing Parameters.** 

The first parameter to select is Target Extraction method. Online Waveform Processing uses the points detected by the device, during data acquisition. This is the simplest target extraction method:

Users may opt to conduct Exponential Decomposition processing. This processing entails creating a polygon encompassing areas in the data set with water. This type of target extraction is optional and covered in the [next section](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/processing-parameters/exponential-decomposition).&#x20;

Set the **Multiple Time Around** setting to **Fixed in Zone 1**:

No settings are necessary for **Pre-classification**:

No **Pre-georeferencing** is necessary:

No **Post-georeferencing** data filters are necessary:

The **Water surface selector** should be disabled, unless[ XDC processing](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/processing-parameters/exponential-decomposition) is enabled:
