Data values from files read by Echoview and data values generated by Echoview can be exported. This is distinct from the export of analysis results from Echoview.
To ensure that you have a permanent record of the calibration setting for each data export, create a read-only export file and save a copy of the Ev file with your export data.
The following data from echograms are available for export on the Echogram menu:
Notes:
Attitude data (Heading, Roll and Pitch) can be exported through a Graph menu.
Position data (GPS) from a Cruise track window or a Table can be exported through the Cruise Track menu or a Table menu.
Distance data (Vessel logs) from a Table can be exported through the Table menu.
Data exports in specific formats are also available:
The data values exported will depend on the type of variable from which you are generating the export, e.g. Sv values will be exported from an Sv variable, TS values from a TS variable. Underlying data values exported will depend upon the file format and what is stored in the data file.
All values are exported with one ping per line in a file of comma separated values file (.csv) See Text data files for information on how you can use these exported data files in Echoview again.
This export is not available from all acoustic variables. See Export file formats for a discussion of different data exports from acoustic variables.
Note: Single beam Sv and Mutlibeam Sv and magnitude variables may also be exported to the Matlab format (*.mat).
To export data values or underlying data for an entire echogram:
On the Echogram menu, point to Export, and then click Values or Underlying data.

Note: The longitude and latitude values that are exported are the longitude and latitude of the GPS antenna at the time the ping was transmitted, see What is affected by transducer geometry for more information.
You can export the following values for all pings or a selection of pings:
echogram data values (data values from the current echogram that were derived by Echoview from the underlying data, e.g. Sv, unspecified dB values)
underlying data values (the values read from the data file)
multibeam bottom detections
Note: Underlying values cannot be exported from variables that were beamformed in Echoview.

On the Echogram menu, point to Export, and then click Underlying data, Data type or Bottom detections.
On the Export Underlying Data dialog box, Export Variable Data dialog box or Export Multibeam Bottom Detections dialog box, select All, or Ping range to enter the pings for which you want to export values.
If you selected Ping range, enter the first and last ping for the range over which you want to export values.
Click Export.
Choose a folder and enter a file name for the export file.
Click Save.

Output is *.points.csv.
To export Georeferenced Sample data from a selection:
Display an acoustic variable.
Use one of the selection tools to make a selection for export.
On the Shortcut menu, point to Export Selection, and click Georeferenced Samples.
When it is a multibeam variable, specify the pings to export.
Enter the filename for your export in the Export data as Georeferenced Samples dialog box.
Output is *.points.csv or *.mb.points.csv (multibeam data).
To export Georeferenced Sample data for a region:
Display an acoustic variable.
On the Shortcut menu, point to Export Region, and click Georeferenced Samples.
When it is a multibeam variable, specify the pings to export.
Enter the filename for your export in the Export data as Georeferenced Samples for Region dialog box.
Output is *.points.csv or *.mb.points.csv (multibeam data).
Each line in the file is described by the .points.csv format.

Single target values can be exported to a comma separated values file (target.csv). The export file will contain the properties for each single target, including; ping date, ping time, target depth, compensated TS, uncompensated TS, minor-axis and major-axis angles (if available), pulse properties, target properties, Exclude below line depth (if available), estimated target properties (if available) and ping number.
Note: Single target variables can be derived from multibeam target detection variables. When such a target.csv file is added to an EV file, its Dataflow object is created in a special way. See the Performance tip note for more information.
To export single targets for an entire echogram:
On the Echogram menu, point to Export, and then click Single Target.
Choose a folder and enter a file name.
Click Save.
To export single targets for a region:
Select the region.
On the Shortcut menu (right-click), point to Export Region, and then click Single Target.
Choose a folder and enter a file name.
Click Save.
To export single targets for a selection:
Make a selection using any selection tool.
On the Shortcut menu (right-click), point to Export Selection, and then click Single Target.

Target length values can be exported from a target length variable to a comma separated values file (length.csv). The export file will contain the properties for each Target length including; Ping date, Ping time, Ping_milliseconds, Target_depth, Target_length (using compensated TS), Target_length_uncompensated, Target_length_manual, Target_class and ping number.

The frequency distribution of single targets within a selection or region can be exported to a comma separated values file (.csv). The export file contains a column for each single target frequency distribution analysis variables and a column for each target strength bin. The column for each bin can contain either the number of targets in a bin and/or the TS mean of targets in a bin. You select which values to export on the Export page of the EV File Properties dialog box).
