Create an Echoview EVR (Region definition) file from depth and time intervals

This function generates Echoview Region definitions according to predefined starting and end depts at given times. The results are save as .EVR file for import into Echoview

Usage

makeEVRfromDT(
  depths,
  times,
  dates,
  rName = "Region",
  rClass = "Selection",
  rType = 1,
  dir = NULL,
  fn = NULL,
  rNotes = list("")
)

Arguments

depths: list of depths (can be multiple regions, where each is a list element)
times: (character) list of times in HHMMSS
dates: list of dates as character %Y%m%d (can be multiple regions, where each is a list element)
rName: = "Region" (character) Name of the region
rClass: = "Selection". character Define class, otherwise it will be Unclassified
rType: = 1 (integer; 0 to 4) see details
dir: = NULL character Path to the output folder
fn: = NULL character Name of the output filename
rNotes: = list("") character Region Notes

Value

saves an Echoview EVR (Region definition) files

Details

The following region types (integer 0 to 4) are available in Echoview 0 - Bad Data (no data); 1 - Analysis; 2 - Marker; 3 - fishtracks; 4 - Bad Data (empty water)

Note

This function is experimental

dates <- list(c(rep("20170901",5)),c(rep("20170901",5)))
dir <- 'F:\\'
fn <- 'imaginaryRegions'
makeEVRfromDT(depths,times,dates,fn=fn,dir=dir)
