wbt_normalized_difference_index: Normalized difference index

In whitebox: 'WhiteboxTools' R Frontend

Normalized difference index

Description

Calculate a normalized-difference index (NDI) from two bands of multispectral image data.

Usage

wbt_normalized_difference_index(
  input1,
  input2,
  output,
  clip = 0,
  correction = 0,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input1	Input image 1 (e.g. near-infrared band).
input2	Input image 2 (e.g. red band).
output	Output raster file.
clip	Optional amount to clip the distribution tails by, in percent.
correction	Optional adjustment value (e.g. 1, or 0.16 for the optimal soil adjusted vegetation index, OSAVI).
wd	Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode	Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters	Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only	Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
