“A Word From our Director”

“A hydrographic survey can determine a minimum depth, under keel clearance, 3D bottom model, capacities and a host of other information. To ensure there are no dangers to navigation, it is important that mariners know precise water depths. We can determine the arrangement of sea floor assets for anchoring, dredging, construction and fisheries habitat. We utilise the latest advanced techniques and equipment to enable precise marine mapping. Total Hydrographics’ marine mapping & GIS services ensure you to get the most out of your investment.

Our clients receive a final product which is clean, efficient and accurately presented.”

Client Testimonials

“ By utilising the technology Total Hydrographic has on offer we were able to visually review the underwater surface to a greater level to what we have been able to do previously.

We were also able to utilise the surface models to gain a greater understanding of the condition of the reservoir to assist in efficient operation.“

We are very satisfied with the quality of product received which addressed all required components of our scope of works. Total Hydrographic met our expectations on this project. I was very satisfied with both the response times and quality of content. Both Tim and Paul answered or responded by phone or email rapidly and chased up further information quickly when requested. We appreciate the very quick turnaround period from securing Total Hydrographic for the job to completion of the report prior to dates outlined in the request for quote.”

 “AECOM Environmental have worked with Total Hydrographic on a recent project in Victoria.  I was very satisfied with the quality of their work.  Tim and Paul both provided quick and comprehensive responses to all questions and requests for modifications to documentation or scope. It was a great service all round and i would employ their services again in the future.  They more than met our expectations and there was nothing that they could have done better.  Definitely recommend – 5/5”

Who We are

Hydrographic Surveys are designed to determine what lies beneath the water’s surface. Hydrographic surveys are also invaluable for protecting the environment and managing it effectively. Hydrographic surveys are used for more than just recreational boating and tourism. In addition to modeling tsunami inundation, they are used to manage coastal zones. Using the info gained from a hydro survey, the area is shaped and dredged. Various events can cause abrupt changes to the submerged area. A hydrographic survey provides valuable information that is used to create topographic maps. This map can be utilized for navigation, drilling, or dredging.

What we do

As part of Total Hydrographics’ Bathymetric Survey System, we employ a range of tools to provide reliable and usable data. There are several tools available

  • Multi-beam enables optimal postprocessing, exceptional mapping, and more dense data.
  • Shallow water areas may be better served by single-beam data.
  • Using Side Scan Sonar (SSS) allows you to examine large areas of water for hazards and features that protrude from the seabed.
  • Our terrestrial survey options complement your hydrographic survey needs so that you have a seamless model.

In recent years, the focus has shifted from collecting data to analysing it, which makes it necessary for qualified hydrographic data scientists to step in.

Our capabilities

Hydrographic surveys can be challenging. Total Hydrographic takes the challenge on head-on. In addition to providing our clients with 100% reliable data, we are committed to the highest levels of quality in all we do.

We can provide you with a cost-effective and accurate hydrographic survey, no matter what your industry or needs are. We have the qualifications, the experience, the skills, and the advanced equipment to ensure your hydrographic survey is completed on time and within your budget.

Hydrography is the science of measuring and describing physical features within water bodies. Hydrography is used for navigation, habitat mapping and hazard identification.
