Calculate band ratio — calculate_band_ratio • HSItools

calculate band ratio of selected wavelengths.

Usage

calculate_band_ratio(
  raster,
  ratio_name,
  edges,
  extent = NULL,
  ext = NULL,
  filename = NULL
)

Arguments

raster: terra SpatRaster of normalized capture data.
ratio_name: character, lower case name of calculated ratio.
edges: numeric vector of two for the (numerator and denominator).
extent: an extent or SpatVector used to subset SpatRaster. Defaults to the entire SpatRaster.
ext: character, a graphic format extension.
filename: NULL (default) to write automatically into products, provide full path and ext to override.

Value
