Calculate mean reflectance (Rmean)

Usage

hsi_calc_rmean(
  x,
  index_name = NULL,
  na.rm = TRUE,
  filename = "",
  overwrite = FALSE,
  ...
)

Arguments

x: A SpatRaster with hyperspectral data.
index_name: Character. Name for the output layer. Default NULL.
na.rm: Logical. Remove NA values. Default TRUE.
filename: Character. Output filename. Default "" keeps result in memory.
overwrite: Logical. Overwrite existing file. Default FALSE.
...: Additional arguments passed to terra::writeRaster().

Value

A SpatRaster with mean reflectance values.
