Echoview 10 beta now available for testing

9 April 2019

Echoview is committed to improving the depth and efficiency of your acoustic data processing, regardless of your processing methodology. We are pleased to introduce features in Echoview 10 that will improve processing speed and simplify your work flow.

Echoview’s beta releases are the perfect opportunity to test and experiment with new features prior to an official release. We recommend that beta versions are not used for crucial data processing, as functionality and calculations may not yet be fully verified...

We welcome feedback on usability and reports of any bugs that you may encounter. Please send details through to support@echoview.com.

New features in Echoview 10 include:

  • The Code operator, with a built-in Python interpreter that can be used for custom algorithm development
  • New echointegration metrics, or analysis variables, that can be included in the Analysis by Regions, Analysis by Cells, and Analysis by Regions by Cells exports:
    • Center of mass
    • Inertia
    • Proportion occupied
    • Equivalent area
    • Aggregation index

  • New analysis variables for altitude, a measure of the distance from the bottom and top of a region to the exclude-below line:
    • Region bottom altitude max
    • Region bottom altitude mean
    • Region bottom altitude min
    • Region top altitude max
    • Region top altitude mean
    • Region top altitude min
  • Line-referenced echograms. Sometimes referred to as a bottom-lock view, this new display option allows you to visually flatten data and provides a new perspective on your echograms.

  • A new export that is compatible with the ICES acoustic trawl survey database in the CSV file format. New fields for required metadata values have also been added to the Transducer and EV File Properties dialogs.
  • The Command interface and Console dialog box: a new way to control Echoview that allows you to read and edit variable properties using a simple, string-based syntax.
  • Much faster calculations for Simrad EK80 pulse compressed data

  • Export of complex values from wideband data to CSV files from regions, selections and echograms.
  • Wideband frequency response data can now be exported for fish track regions in single target detection - wideband echograms.
  • Improvements and additions to the Single target detection - Wideband operator algorithm and settings:
    • A new setting, Minimum target separation, can be used to prevent or reduce the detection of multiple targets from a single object
    • Normalized calculations and settings, including the Minimum and Maximum Normalized Pulse Length operator settings, now use the pulse compressed effective pulse length, which is more appropriate for pulse compressed data than the transmitted pulse length
    • TS of a target is calculated using the peak sample in the identified power pulse
  • Official support for the Kongsberg Mesotech Flexview .imb file format
  • New features that make it easier to explore and bring line data into Echoview:
    • Lines can now be exported to *.depth.csv files when exporting from a line graph, a line table, or a line object on the dataflow (all line points will be included). Export to *line.csv files remains an option when exporting from an echogram window (one line point per ping will be included)
    • Both *.depth.csv and *.line.csv files are supported data file formats and can be added to Echoview Filesets – a much easier entry point than needing to edit *.EVL files in earlier versions of Echoview
  • The Tape measure tool now displays five measurements when measuring distances between two or more points on an echogram:
    • Length straight-line distance
    • Length along-track distance
    • GPS straight-line distance
    • GPS along-track distance
    • Range

  • Efficiently locate data files that can't be found when opening an EV file by right-clicking and choosing to Browse for file.
  • ASL Environmental's AZFP file format can now be used with the automatic creation of transducers for different frequencies and the derivation of raw variables based on frequency features that were introduced in Echoview 9.
  • Threshold offset operator now also allows the detection of the maximum threshold as well as the minimum threshold.
  • Power variables can be used as input to the Background, Transient, and Impulse Noise Removal operators.
  • New shortcut keys:
    • CTRL+SHIFT+P to pre-calculate the values of all samples in the active echogram
    • F9 to show or hide the Details dialog box
  • Other changes include:
    • The maximum value of time separation between grid lines displayed on an echogram has been increased to 99999.99 minutes
    • The single beam line pick algorithms now allow negative start and stop depths for bottom detection
    • The echogram right-click option to Show Information has been removed, and all information that was previously reported in this dialog box can now be found in the Details dialog box

A full list of what is coming in Echoview 10 can be found on the “New in Echoview 10” pages in the help file that's installed with Echoview 10.

Echoview 10 is compatible with Windows 7, Windows 8.1 and Windows 10, and can only be installed on 64-bit editions of these operating systems.

The licensed features in Echoview 10 are available to all license holders with an up-to-date Maintenance and Technical Support (MATS) subscription, but the beta version can also be tested by license holders that have access to Echoview 9. Anyone can download and test the beta version in demonstration mode.

To find out if your MATS subscription is current, please contact sales@echoview.com.
