selbox: Select a box

Description

Selects grid cells inside a lon/lat or index box.

Usage

cdo_selindexbox(
  ifile,
  lon1 = NULL,
  lon2 = NULL,
  lat1 = NULL,
  lat2 = NULL,
  idx1 = NULL,
  idx2 = NULL,
  idy1 = NULL,
  idy2 = NULL,
  ofile = NULL
)
cdo_sellonlatbox(
  ifile,
  lon1 = NULL,
  lon2 = NULL,
  lat1 = NULL,
  lat2 = NULL,
  idx1 = NULL,
  idx2 = NULL,
  idy1 = NULL,
  idy2 = NULL,
  ofile = NULL
)

Value

Operators that output one or more files return a character vector to the output files.

Operators that output an indefinite number of files return a string with the basename of the files.

Operatos that don't return filenames return a character vector with the string output.

Arguments

ifile: String with the path to the input file.
lon1: FLOAT - Western longitude in degrees
lon2: FLOAT - Eastern longitude in degrees
lat1: FLOAT - Southern or northern latitude in degrees
lat2: FLOAT - Northern or southern latitude in degrees
idx1: INTEGER - Index of first longitude (1 - nlon)
idx2: INTEGER - Index of last longitude (1 - nlon)
idy1: INTEGER - Index of first latitude (1 - nlat)
idy2: INTEGER - Index of last latitude (1 - nlat)
ofile: String with the path to the output file.

Details

sellonlatbox  Select a longitude/latitude box
              Selects grid cells inside a lon/lat box. The user must specify the longitude and latitude of the edges of the box.
              Only those grid cells are considered whose grid center lies within the lon/lat box.
              For rotated lon/lat grids the parameters must be specified in rotated coordinates.
selindexbox   Select an index box
              Selects grid cells within an index box. The user must specify the indices of the edges of the box.
              The index of the left edge can be greater then the one of the right edge. Use negative indexing to
              start from the end. The input grid must be a regular lon/lat or a 2D curvilinear grid.
