What's new in version 4.80?
Posted on Wednesday, 14 October 2009 | Permalink
Over the past few months, we have been working steadily towards the release of Echoview version 4.80. The full release is now available to download.
- General enhancements
- Variables & Geometry window enhancements
- COM scripting enhancements
- Tweaks and other changes
General enhancements
Automated region classification
You can now automatically apply region classes to regions using rules based on a region's analysis results (attributes). The new Classification tab on the EV File Properties dialog allows you to create and edit the rules that are evaluated in order to assign classes. Classification can be done automatically after schools detection or manually for a specific region or regions within a selection on an echogram, as well as via the Region Manager.
Above is a screenshot of the EV File Properties dialog box, showing two rules that will apply two region classes. One of these is selected and its conditions are editable in the lower list box.
Hydroacoustics User Forum window
Echoview now contains a new dockable window that shows the most recent posts on the new Hydroacoustics User Forum.
Removal of 500 virtual variable limit
You can now have as many virtual variables in an EV file as you want (we've seen some very large data flows!).
Save as Template
You can now save a copy of your EV file as a template or live viewing template easily via new menu commands on the File menu.
TVG curve available on the ping graph for Sv variables
On Sv echograms, you can now show a TVG Curve on your ping graph using the Shortcut menu. This is useful for faster and more visual Sv background noise estimation.
Variables & Geometry window enhancements
Copy and paste virtual variables, virtual lines and editable lines
This is a long-standing user request! You can now copy and paste items on the Variables & Geometry window. Currently, you can copy and paste virtual variables, virtual lines and editable lines. Objects retain their relationships when they are copied together, and combined with drag and drop of operands (below) this allows very easy duplication of portions of your dataflow within the one EV file, or from one EV file to another!
Drag and drop input operands
The input operands for virtual variables and virtual lines can now be set directly on the Variables & Geometry view. A small node appears when your mouse hovers over an object, and it can be dragged with the mouse to create a new arrow that you can drop onto another object on the view. Objects highlight and dim depending on whether the dragged object is a suitable potential operand. You can either drop the arrow straight on an object, or drop it on an existing input operand’s arrow to replace that specific operand.
This is also useful when pasting virtual variables or lines, as you can easily hook up complex sets of variables and lines after pasting them into an EV file.
Drag tabs to reorder
You can now drag and drop the tabs at the bottom of the Variables & Geometry window to reorder your views.
COM scripting enhancements
- Support for the 'Inherit calibration settings from' settings on the Calibration page of the Variable Properties dialog box for virtual variables
- Support for shifting regions in depth or time
- Support for pre-reading data files - handy for generating EVI files for large quantities of data
- Support for editable lines and picking lines, including line pick properties
- Support for filesets' time offset property
These enhancements will help you automate your data processing.
Plus many more other tweaks and useful changes
- Line usage information able to be shown on the Variables & Geometry window
- A keyboard shortcut to create a marker region at the last ping without having to select the data (especially useful when live viewing)
- The tape measure tool's displayed measurement should stay away from the feature you are measuring
- And much more...
As always, in version 4.80 we have tried to select a balance of enhancements that will have maximum usefulness across our broad and diverse user group. If there are any new features here that make a real difference for you, we'd love to hear about it! Likewise, if there are features that we don't have and that you'd like to see implemented, or if you would like to know more about the new features, please contact Echoview support.
We hope you enjoy this new release!
