# Bathymetric LiDAR Processing in RiProcess

This document pertains to processing HydroRanger data in Riegl's RiProcess software. The workflow is as follows:

1. Use either [InertialExplorer ](https://docs.phoenixlidar.com/3rd-party-software-documentation/inertialexplorer-desktop-8.70-8.90-processing)or [NavLab ](https://docs.phoenixlidar.com/spatialexplorer-8-and-9/user-interface/toolbars/workflow/navlab-embedded)to create a processed trajectory in POF format. 
2. [Create a project in RiProcess](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess):
   1. Assign coordinate system
   2. [Create navigation device](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-a-navigation-device)
   3. [Add trajectory (POF format)](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-a-trajectory)
   4. [Add lidar records](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-records)
   5. [Add processing parameters](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/processing-parameters)
   6. Assign records
   7. [(optional) Add control objects](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-control-objects)
3. [Run Data Processing Wizard](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/data-processing-wizard)
4. [Run RiPrecision](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/riprecision)
5. [Execute RiHydro processing steps](https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/rihydro-workflow):
   1. Classify noise
   2. Classify water surface points
   3. Create water surface
   4. Execute refraction correction of bathymetric points
6. (Optional) Colorize the scan
7. Export LAZ format pointcloud
