Exporting multibeam target data
You can export multibeam targets for all pings or a selection of pings to a .csv file. The targets.mb prefix is added to the csv file extension (e.g., filename.targets.mb.csv).
To export multibeam targets
- Display a multibeam targets echogram.
- On the Echogram menu, point to Export, and then click Multibeam target to CSV.
- On the export dialog box, specify the Export options.
- Click Export...
Multibeam target export file format (*.targets.mb.csv)
The first line of the file is a header row that contains the names of the variables that are exported (see below). Each additional row contains the corresponding variables for a single ping.
|
Variable |
Description |
|
Ping_index |
Sequential ping number Note: In Echoview, pings are renumbered sequentially beginning with 0 |
|
Distance_gps |
Distance (nmi) from the first GPS fix in the data file |
|
Distance_vl |
Vessel log (nmi) at the time the ping was transmitted |
|
Ping_date |
The date (yyyy-MM-dd) on which the ping was transmitted |
|
Ping_time |
The time (HH:mm:ss) at which the ping was transmitted |
|
Ping_milliseconds |
The millisecond component of Ping_time (0..999) |
|
Latitude |
The latitude (degrees) of the GPS antenna at the time the ping was transmitted |
|
Longitude |
The longitude (degrees) of the GPS antenna at the time the ping was transmitted |
|
Heading |
The heading of the platform at the time the ping was transmitted Note: Heading values are taken from the heading source selected on the Attitude page of the Platform Properties dialog box. |
|
Range_start |
Range (m) of the closest sample (measured along the beam-axis) in the operand variable. |
|
Range_stop |
Range (m) of the farthest sample (measured along the beam-axis) in the operand variable. |
|
Sector_angle |
Angle (degrees) scribed between the two outer beams in the operand variable. |
|
Number_of_beams |
Number of beams in each ping in the operand variable. |
|
Number_of_targets |
Number of targets in the ping. |
|
Ping_mode |
Ping mode of the multibeam target variable. |
|
Variable_name |
Name of multibeam target variable. |
|
Datafile_ping_number |
The number, if any, assigned to the ping in the original data file from which Echoview read the data. |
|
Target values Note: No title in the header row of the file |
A string of comma-separated
values comprising each target according to the format (line breaks for clarity only): <target 0 range>,<target 0 mean Sv >,<target 0 major-axis angle>,<target 0 minor-axis angle>,<target 0 status>, <target 1 range>,<target 1 mean Sv >,<target 1 major-axis angle>,<target 1 minor-axis angle>,<target 1 status>, ... <target n range>,<target n mean Sv >,<target n major-axis angle>,<target n minor-axis angle>,<target n status> where n = Number_of_targets - 1. |
