wbt_normalized_difference_index: 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 = FALSE,
  compress_rasters = 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.

verbose_mode

Sets verbose mode. If verbose mode is False, tools will not print output messages.

compress_rasters

Sets the flag used by WhiteboxTools to determine whether to use compression for output rasters.

Value

Returns the tool text outputs.
