Multibeam Processing

Flexible Workshop Tailored to Your Multibeam Experience

From Fundamentals to Field Expertise

A 5-day practical workshop with an optional at-sea component, designed to help hydrographers sharpen their understanding of multibeam systems—fast. Learn to optimize sonar settings, manage uncertainty, and make confident, data-driven decisions in the field and at your desk.

Refine your processing workflow and deliver better results.

This course helps hydrographers move from raw data to final deliverables with clarity and control. Learn how to identify and fix common issues, apply effective cleaning techniques, and produce survey-grade outputs. Ideal for anyone looking to sharpen their post-acquisition skills and improve survey turnaround.

“This is a MUST DO course for anyone in the hydrographic surveying industry. The course content and Jonathan's delivery methods provide a perfect combination for a deeper understanding of the theoretical aspects of hydrographic surveying—and how to apply that understanding in the real world. A great course to help with troubleshooting, everyday field decisions, and best practices.”
— Rafe Penington, Multibeam Crash Course

Who It’s For

Designed for hydrographers, surveyors, and technical teams who want to:

  • Improve survey data quality and efficiency

  • Confidently adjust sonar settings in the field

  • Understand multibeam fundamentals and apply them in practice

Key Outcomes

By the end of this course, participants will be able to:

  • Estimate object detection and resolution with confidence

  • Balance vessel speed, swath width, and ping rate for targeted density

  • Anticipate and adapt to uncertainty in real time

  • Apply practical, sensor-specific advice from field-tested methods

Our Process

Before the Course 

Attendees complete a questionnaire to identify skills, pain points, and goals. Curriculum is tailored accordingly.


During the Course 

Customized instruction mixes theory, field-tested workflows, and participant-driven Q&A. Optional vessel day ensures direct application.


After the Course 

Participants set individual and team development goals. A follow-up session (3–6 months later) helps track progress, share outcomes, and ensure accountability.

Prerequisites

Participants should have basic familiarity with hydrographic survey systems and workflows, ideally with at least one field season of experience. The course is suitable for a range of participants—from early-career professionals looking to build core competencies to seasoned practitioners seeking to refine techniques and troubleshoot more effectively.

What You’ll Learn

Sonar Controller & Acquisition Systems 

Quick tour, key functionality

Resolution:
  • Imaging geometry, beamwidth, beam steering, pulse length/type, sensor-specific advice

Density:

  • Speed, swath geometry, ping rate, real-time monitoring, motion effects, line planning, stabilization

Uncertainty: 
  • Accuracy standards, TPU, adaptive survey practices, human error mitigation

Backscatter: 
  • Fundamentals, impact of sonar settings, acquisition best practices (general, sensor-specific, software-specific)

(5-days in-class + optional 1 day at sea on your vessel with your hardware/software)

Core Topics Include

System Fundamentals & Sonar Geometry
  • Overview of multibeam echo sounder systems

  • Understanding beam steering, beamwidth, and pulse types

  • Sound velocity profiles, refraction effects, and depth calculation

  • Practical visualizations to explain how the system “sees” the seafloor

Resolution & Density
  • How to control and evaluate resolution

  • Trade-offs between speed, swath width, ping rate, and line planning

  • Motion compensation, stabilization, and survey optimization

  • Real-time monitoring techniques for better data outcomes

Uncertainty & Accuracy
  • Total Propagated Uncertainty (TPU): what it is and how to manage it

  • Accuracy standards (IHO, CHS, etc.) and real-world implications

  • Human error and sensor integration challenges

  • Adaptive survey techniques for changing conditions

Processing & QA/QC Best Practices
  • Initial bathymetry cleaning and QC workflows

  • Feature detection and seafloor classification basics

  • Data troubleshooting: identifying and correcting errors at source

  • Communicating data quality internally and to clients

Sensor-Agnostic & Sensor-Specific Strategies
  • Universal principles applicable across all multibeam systems

  • Optional deep dives into vendor-specific workflows and tools (based on group needs)

Optional At-Sea Component
  • Reinforce learning with an applied day on the water, using your own hardware and software setup. Get expert feedback on acquisition techniques, sonar settings, and real-time decisions.

Venue

For maximum impact and team engagement, onsite delivery is encouraged. The course can also be delivered fully online with all participants joining remotely, or as a hybrid model with a mix of in-person and virtual attendees. On-vessel components are tailored to your equipment, location, and operational goals.

Duration

5-days classroom-based instruction

  • Optional 1-day at sea (on your vessel, using your hardware and software)
