Mosaic to pliman — mosaic_to

Convert an SpatRaster object to a Image object with optional scaling.

Usage

mosaic_to_pliman(
  mosaic,
  r = 3,
  g = 2,
  b = 1,
  re = 4,
  nir = 5,
  rescale = TRUE,
  coef = 0
)

Arguments

mosaic: A mosaic of class SpatRaster, generally imported with mosaic_input().
r: The layer for the Red band (default: 3).
g: The layer for the Green band (default: 2).
b: The layer for the Blue band (default: 1).
re: The layer for the Red-edge band (default: 4).
nir: The layer for the Near-infrared band(default: 5).
rescale: Rescale the final values? If TRUE the final values are rescaled so that the maximum value is 1.
coef: An addition coefficient applied to the resulting object. This is useful to adjust the brightness of the final image. Defaults to 0.

Value

An Image object with the same number of layers as mosaic.

Details

This function converts SpatRaster into an Image object, which can be used for image analysis in pliman. Note that if a large SpatRaster is loaded, the resulting object may increase considerably the memory usage.

Examples

library(pliman)
# Convert a mosaic raster to an Image object
mosaic <- mosaic_input(system.file("ex/elev.tif", package="terra"))
pliman_image <- mosaic_to_pliman(mosaic)
plot(pliman_image)
