# 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 ](/3rd-party-software-documentation/inertialexplorer-desktop-8.70-8.90-processing.md)or [NavLab ](/spatialexplorer-8-and-9/user-interface/toolbars/workflow/navlab-embedded.md)to create a processed trajectory in POF format. 
2. [Create a project in RiProcess](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess.md):
   1. Assign coordinate system
   2. [Create navigation device](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-a-navigation-device.md)
   3. [Add trajectory (POF format)](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-a-trajectory.md)
   4. [Add lidar records](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-records.md)
   5. [Add processing parameters](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/processing-parameters.md)
   6. Assign records
   7. [(optional) Add control objects](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/creating-a-project-in-riprocess/adding-control-objects.md)
3. [Run Data Processing Wizard](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/data-processing-wizard.md)
4. [Run RiPrecision](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/riprecision.md)
5. [Execute RiHydro processing steps](/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/rihydro-workflow.md):
   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
