EchoView

Echoview 5.0

What is EchoView?

Echoview is an advanced hydroacoustic data-processing application for fisheries scientists and environmental managers who need to monitor and understand aquatic environments.
It provides the ability to quickly and easily visualize, process and characterize the data from a wide range of echosounder and sonar systems with an extensive range of user-definable algorithms.
Echoview is unsurpassed in its scope, power and flexibility and has been widely adopted as the global industry standard for fisheries acoustics and related studies.

Echoview comprises a base system and a number of optional modules suitable for different applications. Since its launch in 1995, Echoview has focused on the processing of water-column hydroacoustic data, specializing in, but by no means limited to, scientific-fisheries and environmental-management applications.

Echoview is developed and supported by the staff at Myriax Software in Hobart, Australia. Myriax Software is a wholly owned subsidiary of Myriax Pty Ltd, headquartered "down under, down under" in Tasmania.

Application based on Echoview

Biomass

The Task : Stock assessment of aggregated fish and zooplankton in marine and other environments.

The Solution : Use the most powerful classification tools available for partitioning your data, calculating fish densities according to species, and determining indicative parameters for behavioral and other studies. Work with data from all commonly used echosounders and access the analysis methods employed by leading institutes around the world.

Species ID

The Task : Species identification and echogram classification for biomass estimates in marine and other environments.

The Solution : Define and automate the identification of different classes of scatterers. Use single or multiple frequency methods by employing a powerful suite of virtual echogram operators along with filtering, school detection, single target detection and target tracking algorithms. Echoview provides a highly efficient visual environment for you to develop echo classification solutions and enables access to the shared methods of colleagues.

Fish Counting

The Task : Stock assessment and behaviour studies of individual fish in rivers and other environments.

The Solution : Detect, track and count fish (working with single or multiple frequencies) using a single application that provides you with full control of the entire process. Calculate biomass, distribution, flux, and indicative parameters for behavioral studies and species identification. Work with data from singlebeam, multibeam and DIDSON sonars and access then analysis methods employed by leading institutes around the world.

Fish Habitat

The Task : Identify fish habitat and seabed types and link echograms to other classification data.

The Solution : Define and automate the calculation of different indices from seabed backscatter and use them to classify bottom habitat or substrate type of the seabed. Use single or multiple frequency methods by employing a powerful suite of virtual echogram operators along with data filtering and thresholding. Import and view the results of other seabed acoustic classification systems (or classifications based on other data such as video and benthic grabs) along with your echograms for visual verification. Use Echoview’s highly efficient visual environment to develop or verify seabed classification solutions and export data to Quester Tangent’s Echo IMPACT seabed classification software.

Multibeam Sonars

The Task : Improve biomass estimates, study fish behavior and identify species using multibeam sonars.

The Solution : Multibeam (swath) sonar systems and Echoview 3D visualization and analysis are the future of acoustic surveys for fisheries applications. Use advanced multibeam data processing and visualization tools and analyze split beam echosounder data in a single integrated package. Work with water column data from most multibeam sonars, scanning sonars and the DIDSON acoustic camera to extend your research capabilities. Exploit the opportunity to influence the design and content of Echoview’s multibeam functionality as development continues.

DIDSON

The Task : Detect, count, measure and identify fish echoes in DIDSON acoustic camera data

The Solution : Echoview sonar modules provide powerful and advanced analysis of data from DIDSON acoustic cameras for detection and analysis of fish in rivers, lake and marine environments. Advanced and flexible signal processing tools allow fish objects to be extracted from background noise. Advanced fish detection uses full beam data; simple beam-crossing techniques available. Fully synchronize simultaneous data from DIDSON and split beam echosounders for visualization and analysis. Exploit the opportunity to influence the design and content of evolving Echoview functionality for DIDSON and similar instruments.
