New in Echoview 3.50 for all users
Welcome to Echoview 3.50!
Echoview 3.50 continues to enhance your manipulation and visualization of data and streamline your workflow. A number of enhancements and features requested by specific individuals or organizations have been added and we hope they will prove to be of general use. Our favorite features are: the new setting that automatically applies calibration values from Simrad Ex60 .raw files; our new file management features; live viewing enhancements that allow 2D school detection in real time, selections and linked graphs to update when new data arrives during live viewing; ping by ping multibeam object detection and the variety of powerful new operators and operator enhancements.
New features are presented in two categories:
New features for all users
New features for users of specific echosounders
New features for all users
Feature |
Benefit |
Improved file management |
New file management features which allow you to specify the default locations presented in various Open, Save, Import and Export dialog boxes and the folders in which Echoview will look for data files. Configure your favorite locations and save time during Echoview file interactions. This significantly improves upon (and replaces) the Ignore data-file paths setting which was on the EV file page of the EV file properties dialog box earlier versions of Echoview. |
Selections move or grow with new live viewing data |
Rectangular selections now have the ability to advance or extend their vertical boundaries as live viewing data arrives. Graphs linked to moving selections will update as the selection advances or extends. This feature saves time during calibration runs and makes it easier to monitor data during live viewing. |
View single targets and fish tracks in 3D scenes |
Create 3D Single targets and 3D Fish tracks from single target echograms and view them in scenes. Use the advantages of navigating in time and space to see clearly what your fish are doing. |
Ping by ping multibeam object detection | A new By ping school detection algorithm is available which will create one 3D region for each object detected in each ping of multibeam data. This provides an alternative to the existing Multibeam target detection operator, conserving information about the shape of individual targets. 3D Region tracking can then be used to track individual targets from ping to ping. |
New operators and operator enhancements |
These new operators and enhancements to existing operators, increase the usefulness of virtual variables for your data processing and analysis.
Two new operator features introduced specifically to aid in the removal of stationary background features from multibeam data:
|
User interface enhancements |
These enhancements give you more control over Echoview's workspace and makes your work easier by giving you easily accessible information about your data.
A very useful enhancement, when working with large data sets and/or long chains of virtual variables, is to press ESC to interrupt virtual variable calculations. This will save you time with respect to waiting for a calculation to finish (because you want to do something else) or just wanting to abort a calculation. |
Scene enhancements |
These enhancements give you more control over scenes, further aiding in data visualization.
|
Cruise track enhancements |
These enhancements will make your work with Cruise tracks easier:
|
New scripting features |
Use new automated processing commands to save time.
See Using the scripting module (deprecated scripting model for Echoview 5.0) for more information. |
Support for new HAC tuple |
Echoview now supports the reading and writing of the HAC split beam detected single target tuple. SciFish Inc. are implementing support of this file format for their echosounders. Please contact SciFish for further details. Note: The above file format is in beta release. |
Extended salinity range for Sonar calculator |
The Sonar calculator now accepts salinity values outside the valid range specified by the sonar calculator algorithms. In these cases, results are displayed with accompanying warnings. |
Improved fish track detection |
The following improvements to our fish track detection feature are:
|
Geotiff export times improved |
Large Geotiff exports of scenes are now faster thanks to some performance enhancements in this area. |
FastMM 4.46 memory manager | Echoview now comes with the FastMM 4.46 compiled memory manager. FastMM 4.46 provides improved memory management for Echoview on your computer which enables Echoview to run faster, saving you time when you process large quantities of data. |
Changes to Export variable names |
To avoid the ambiguity that the term centroid can lead to, the 3D region metrics Centroid_latitude, Centroid_logitude and Centroid_depth are named Geometric_center_latitude, Geometric_center_longitude and Geometric_center_depth. |
Documentation enhancements | This help file, aside from documenting all these new features in detail also gained:
