General Course Overview:  
This course will discuss concepts, methodologies, and theory of:

  • bathymetric systems 
  • systems installation
  • sensor linear and angular offsets
  • relationships of sensor to vessel center of rotation
  • localizing water surface 
  • sound speed measurements for sonar refraction corrections
  • GNSS corrections
  • GNSS/INS alignment calibrations
  • multibeam alignment calibrations (aka patch test)
  • accuracy validation process
  • precision & bias measurement process
  • continual checks required throughout a bathymetric survey
The above is a heavily condensed version of our 40-hour training program.  However, it will offer the students a review or introduction to critical elements required of a high-resolution bathymetric single and multibeam survey.

This course qualifies for 4 Professional Development Hours (PDH's). Certificates will be issued via email upon request.

Who Should Attend?
This program brings practical process-oriented training for those that need to validate or contractually appreciate bathymetric survey data accuracy and precision and how this jives with survey specifications.  

About the Instructor: 

The Bathymetric Mapping course will be presented by Mike Mutschler. Mike has a background in Geomatics Engineering and has had roles in cadastral land surveying, establishments of control networks,  bathymetric mapping in over 30 countries and throughout the USA, Mr. Mutschler runs a small consulting and training company from Portland, Oregon serving North American mapping agencies and businesses.  

This course is being offered by WEDA as part of our mission to share knowledge and information about dredging. Because WEDA is a non-profit organization, with its goal not to make money but to share information, WEDA is offering this course at a low cost of $150.
