Exporting time series data

Time series and time series collection data can be exported from Echoview to a *.csv file or in some cases to an Echoview Data File Format file (.evd). Note, that an exported CSV file name may have an appended descriptor before the file extension.

When you export a time series collection, Echoview writes a single multi-series table file (*.table.csv) that can be added to a fileset.

Time series export file formats include:

Format	Extension(s)	Add to a fileset?	Notes
Depth values	`*.depth.csv`	Yes	Sampled line depths (export)
GPS fix data	`*.gps.csv`	Yes	Fileset-compatible
Heading	`*.heading.csv`	Yes	Bearing time series
Interval analysis data	`*.analysis.csv`	No	Time series of a specified Sv, single targets or bottom feature analysis variable within a specified interval.
Interval analysis - Calibration data	`*.calibration.csv`	No	Time series of a specified calibration setting within a specified interval.
Length data	`*.length.csv`	Yes	Length time series
Line data	`*.line.csv`	Yes	Ping-by-ping line depths
Pitch	`*.pitch.csv`	Yes	Pitch time series
Roll	`*.roll.csv`	Yes	Roll time series
Speed	`*.speed.csv`	Yes	Speed-through-water
Time series collection	`*.table.csv`	Yes	Multi-series table format used for time series collections. Time series collections can be exported from Echoview to a single `*.table.csv` file and can also be authored externally and added to a fileset. To export a single time series, export a time series variable (e.g., a Time series select operator output) instead of a collection.
Transmission time series select	`*.csv`	No	Transducer transmission characteristic voltage/current/impedance/phase; legacy “Impedance statistic”.
Unspecified time series	`*.custom.csv`	No	Export from Time series select (output type: Virtual unspecified time series); time-stamped values with status; export-only.
Vessel logs	`*.logs.csv`	No	Distance log (export)

To export time series or time series collection variable data:

On the Dataflow window, select the time series or time series collection variable, right-click and on the Shortcut menu select Export, To CSV...

- OR -

On the Dataflow window, select the time series or time series collection variable, right-click and on the Shortcut menu select Graph.
On the Graph menu, click Export To CSV... or Export to Echoview Data File Format...

- OR -

On the Dataflow window, select the time series or time series collection variable, right-click and on the Shortcut menu select Table.
On the Table menu, click Export To CSV... or Export to Echoview Data File Format...

- OR -

On the Dataflow Toolbox, drag and drop the Measurements - CSV exporter onto the Dataflow window.
On the Operands page, specify a time series or time series collection for Operand 1 from the Operand 1 list.
On the Measurements - CSV page, specify the exporter settings.
Click OK.
Double-click the Measurement - CSV exporter object to output to a specified file path and name. An exporter allows you to configure, remember and repeat an export.

Notes:

An unspecified time series is output by a Time series select operator and contains unitless data. For further information refer to About time series collections.
