plot_rgb_raster: Create multi-band raster RGB plot

In geospatialsuite: Comprehensive Geospatiotemporal Analysis and Multimodal Integration Toolkit

Create multi-band raster RGB plot

Description

Create RGB plots from multi-band rasters using terra's native RGB plotting. Reliable and fast without external dependencies.

Usage

plot_rgb_raster(
  raster_data,
  r = 1,
  g = 2,
  b = 3,
  stretch = "lin",
  title = "RGB Composite",
  output_file = NULL,
  verbose = FALSE
)

Arguments

raster_data	Multi-band SpatRaster or file path
r	Red band index (default: 1)
g	Green band index (default: 2)
b	Blue band index (default: 3)
stretch	Stretch method: "lin", "hist", "minmax", "perc"
title	Plot title
output_file	Optional output file path
verbose	Print progress messages

Value

NULL (plots directly to device) or file path if saved

Examples

## Not run: 
# These examples require external data files not included with the package
# True color composite
plot_rgb_raster(satellite_data, r = 3, g = 2, b = 1, title = "True Color")

# False color composite with histogram stretch
plot_rgb_raster(landsat_data, r = 4, g = 3, b = 2, stretch = "hist",
               title = "False Color Composite", output_file = "rgb_composite.png")

## End(Not run)
