Exporting roll data

Roll data can be exported from Echoview to a *.roll.csv file or to an Echoview Data File Format file (.evd).

To export roll data:

Display the roll graph for the variable from which the data is to be exported.
On the Graph menu, click Export Roll Data... or Export to Echoview Data File Format...

- OR -

Display the roll table.
On the Table menu, Click Export Data... or Export to Echoview Data File Format...

The exported roll data can be added to an EV file.

Roll data export file (*.roll.csv)

The first line of the .roll.csv file lists the variables that are exported (these will be used as column headings if the file is loaded into a spreadsheet program). Each subsequent line contains the values for each variable for a single roll determination.

The following data are exported.

Variable	Description
Roll_data	A sequential number
Roll_date	yyyy-MM-dd
Roll_time	HH:mm:ss
Roll_milliseconds	ms
Roll_angle	degrees (output to 3 decimal places). Measured as a clockwise rotation of the major axis about the minor axis when viewed in the positive direction of the minor axis.

Note: Files in this format (.roll.csv) can be added into an EV file and read by Echoview as a raw variable.
