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
  • Sv pings
  • TS pings
  • angular position pings
  • DataType* multibeam pings
  • position GPS fixes
  • heading data
  • line data depth
  • roll data
  • pitch data
  • vessel logs
  • 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

  • * Exported multibeam acoustic data type from the Notes page of the Variable Properties dialog box.
  • See also Wideband variable note about no data, bad data and thresholding.
