Version 5 is coming!

Posted on Tuesday, 24 August 2010 | Permalink

The planning and designing of Echoview version 5 is underway.  We are rebuilding the technological architecture of Echoview to give us a solid base for the next five years of development.  We aim to bring you the most useful and advanced acoustic visualization and analysis software in the world.

The new work includes:
 

• COM Scripting tutorial for the Echoview website
  
  
  

• User interface enhancements - color legend pane on echograms, more options for window docking, streamlined filesets window
  
  
  
  
  
  
  
  
   
• Multithreading - background reading of files, phased in performance improvements for operators
  
  
   
• Terminology review in Help file and in the Echoview user interface.  Streamline and enhance module and licensing information
  
  
  
   
• Continued development of the COM objects
   

Echoview 5 is currently planned for release in late 2010. 

We are interested to hear your opinions on features that would enhance or provide avenues to expand your work if they were added to Echoview. 

As always we will be implementing specific requests and other useful general items.  We look forward to bringing you yet another value-packed Echoview release.

We would also like to hear from you in regard to your requirements and future plans.  Suggestions for specific features and outlines of your future data processing requirements are always welcome, and can benefit the whole community.  Please continue to send your suggestions and ideas to support@echoview.com.

New features and other improvements to COM automation in Echoview 4.90

Posted on Wednesday, 18 August 2010 | Permalink

We have made a number of improvements to Echoview's COM functionality since the initial release of version 4.90, as detailed below.

Optional Parameters:

Using ExportIntegrationByRegions as an example, this method takes two parameters: string FileName and EvRegionClass, as documented in the help file. The FileName parameter must be specified, but the EvRegionClass parameter can either be used to identify regions that match a region class of interest, or you can specify 'Nothing' to export all regions, and is called an optional parameter. Specifying 'Nothing' works in VBScript but the equivalents do not work in MATLAB, Python, R and potentially some other programming languages. To deal with this difficulty we have added new methods without this optional parameter for situations when you wish to export all regions or region classes.

So in addition to ExportIntegrationByRegions, we have now added the new method ExportIntegrationByRegionsAll, which takes only FileName as a parameter. We have added similarly-designed new methods for all other commands that have optional parameters. The complete list of new methods is:

• ExportIntegrationByRegionsAll (string FileName)
• ExportIntegrationByCellsAll (string FileName)
• ExportIntegrationByRegionsByCellsAll (string FileName)
• ExportSingleTargetsByRegionsAll (string FileName)
• ExportSingleTargetsByCellsAll (string FileName)
• ExportSingleTargetsByRegionsByCellsAll (string FileName)
• ExportFrequencyDistributionByRegionsAll (string FileName)
• ExportFrequencyDistributionByCellsAll(string FileName)
• ExportFrequencyDistributionByRegionsByCellsAll (string FileName)
• ExportFishTracksByRegionsAll (string FileName)
• ExportFishTracksByCellsAll (string FileName)
   

These new methods will be added to our documentation soon.
 

New features:

We have also added the following new features to COM:

• New method ExportFrequencyDistributionBySingleRegion
• New method ExportIntegrationBySingleRegionByCells
• The method CreateCurtain now has an optional ping sampling factor parameter

Bug fixes:

The following COM features had problems, but have been fixed in Echoview since the initial release of version 4.90.44. We recommend updating to the latest version if you use COM scripting.

• Removing data files from a fileset
• Exporting 3D objects
• Creating line-relative regions
• Exporting multibeam variable data to MATLAB format
• Exporting an integration by region by cell for a single region
• Exporting data for a single region
• Detecting a surface from a line with an intensity source specified
• The MaximumHorizontalLink property in SchoolsDetection2D

Travel update for July

Posted on Friday, 30 July 2010 | Permalink

Recently there have been several opportunities for members of our Echoview team to attend training courses and visit our customers overseas.

Our product manager Toby Jarvis has been visiting customers throughout Europe since mid June.  The purpose of Toby's trip is to touch base with existing customers and others who may have an interest or a need for Echoview. It has meant that Toby is able to get out and discuss what our customers need in regard to hydroacoustic data-processing, Echoview and general acoustic processing. Toby will be back in the office in mid August. 

David Millington from the development team has just returned from the USA where he attended the National Marine Fisheries ME70 workshop.  Another member of  the development team, Alison Wilcox, will be travelling to Tonsberg in Norway to attend a 6 day fisheries acoustic training course.  This course is being held by Simrad and MAREC and runs from the 29th of August until the 3rd of September.

New example script: Changing variable properties in multiple variables in multiple EV files

Posted on Wednesday, 23 June 2010 | Permalink

A new example script has been added to our Automation via Scripting page.

This script, Changing variable properties in multiple variables in multiple EV files.vbs, shows you how to change settings in the Variable Properties dialog for a number of variables in a number of different EV files.

If you have any questions about the script, you are invited to join in on the thread on the fisheriesacoustics.com forum.

Happy scripting!

Plans for Echoview version 5 and beyond

Posted on Wednesday, 5 May 2010 | Permalink

Since we brought you Echoview 4.00 in September 2006, we’ve been building on implemented technological changes to bring you major new features such as COM automation; region classification; improvements to single beam, multibeam and imaging sonar; improvements to lines and line editing, performance, and calibration; support for new instruments and formats, and user interface and usability changes in many areas. We aim to provide the best new features we can for a wide range of customers, and keep Echoview on a solid technological and scientific foundation.

After four years of working on Echoview 4, we are now planning Echoview Version 5!  As with the release of Echoview 4, we intend to focus on the core technological architecture of Echoview to give us a solid base for the next five years of development. We want to keep bringing you the most useful and advanced acoustic visualization and analysis software in the world.

New features to appear in the next release are still under consideration, but some specific features that we are currently planning to focus on include:

•    Fundamental changes to take advantage of modern multi-core hardware. This will result in massive performance improvements, especially for virtual variables, over the next versions of Echoview.
•    Fundamental changes to Echoview’s architecture. Most of these changes are unlikely to be very visible but will result in great improvements in what we can create within Echoview.
•    A review of all technical terms in Echoview. The aim is to bring consistency to terminology and updates to match any recent changes in the acoustic community.
•    User interface changes. To ensure you get clear and accurate access to your data, and let you perform data analysis and manipulation easily and simply.

Echoview 5 is currently planned to be released in late 2010.

We are interested to hear your opinions on features, if added to Echoview, which would enhance your work or provide avenues to expand your work.

As always we will be implementing a range of specific requests and other useful items with general appeal. We look forward to bringing you yet another value-packed Echoview release.

We also seek feedback about your requirements and future plans. Suggestions for specific features and outlines of your future data processing priorities are always welcome, and can benefit the whole community. Please continue to send your suggestions and ideas to Echoview support.
