Raw variables derived from BioSonics data files

This page describes the variables that Echoview can derive from BioSonics data files.

.DT4 data files from DT4000 single beam echosounders

Echoview can derive the following variables from .DT4 data files logged by BioSonics DT4000 single beam echosounders:

Sv single beam pings
TS single beam pings
position GPS fixes

.DT4 data files from DT5000 dual beam echosounders

Echoview can derive the following variables from .DT4 data files logged by BioSonics DT5000 dual beam echosounders:

Sv dual beam pings (narrow beam) (channel n)
Sv dual beam pings (wide beam) (channel n)
TS dual beam pings (narrow beam) (channel n)
TS dual beam pings (wide beam) (channel n)
position GPS fixes

.DT4 data files from DT6000 split beam echosounders

Echoview can derive the following variables from .DT4 data files logged by BioSonics DT6000 split beam echosounders:

Sv split beam pings (channel n)
TS split beam pings (channel n)
Angular position split beam pings (channel n)
position GPS fixes

Legend

n = channel number
