RiHYDRO Hydrography Laser Scanning Software

For smooth processing of scan data acquired with RIEGL hydrography laser scanners, the airborne data processing software add-on RiHYDRO is offered as a supplement to RiPROCESS.

When processing bathymetric laser data, additional processing steps have to be applied since both the laser beam’s refraction at the air-water interface and the lower propagation speed within the water column must be taken into account in order to obtain a geometrically correct point cloud. Those specific processing steps - usually called "refraction correction" - have to be carried out for each flight strip right after the standard ALS processing workflow.

Main Features  · Main Applications

Main Features
  • Automatic classification of water surface points
  • Generation of a water surface model (WSM) based on classified water surface points
  • Refraction correction of points below the water surface model (WSM)
  • Support of different import and export formats for classification purposes
  • Use point clouds from different scanners to identify water surface points
  • Import externally generated WSM
  • Processes a large number of files for unattended operation in batch mode
  • Smoothly integrated into RiPROCESS
  • Specific software licence required

Main Applications
  • The Airborne Data Processing Software AddOn RiHYDRO has been designed and developed for commercial hydrographic and bathymetric surveying applications.
  • Export Classification:
    • RiHYDRO is subject to export restrictions as set up by the Wassenaar Arrangement. It is classified as dual-use good according position number 6D2 of the official Dual-Use-List to be found on the site http://www.wassenaar.org. Within the European Union, council Regulation No. (EC) 428/2009 implements the export restrictions of the Wassenaar Arrangement. The corresponding position number is 6D002.
