Raw variables derived from Echoview Data File Format files
Files (*.evd) containing Echoview Data File Format data
Echoview can derive the following variables from .evd files:
- Power dB pings (single beam)
- Sv pings (single beam)
- TS pings (single beam)
- Unspecified dB pings (single beam)
- Boolean pings (single beam)
- Single target data
- Multibeam Power dB pings
- Multibeam Sv pings
- Multibeam TS pings
- Multibeam unspecified dB pings
- Multibeam boolean pings
- angular position pings
- position (GPS fixes)
- heading data
- roll data
- pitch data
- line data depth
- vessel logs
- Speed data
- Length data
- Power dB wideband pings
- Sv wideband pings
- TS wideband pings
- angular position wideband pings
- Power dB pulse compressed wideband pings
- Sv pulse compressed wideband pings
- TS pulse compressed wideband pings
- angular position pulse compressed wideband pings
Acoustic variables may also include Tn and (channel m) identifiers
where:
- n is an integer representing the transducer number
- m is an integer representing the channel number
Notes:
- These multibeam data types correspond to supported exported types listed on the Notes page of the Variable Properties dialog box. Some multibeam data types, such as color image or raw beam data, are not currently supported in EVD.
- See also Wideband variable note about no data, bad data and thresholding.
