Generate Ridgeline Plots from Satellite Raster Data

Description

This function generates ridgeline plots from stacked satellite imagery data.

Usage

im.ridgeline(
  im,
  scale,
  palette = c("viridis", "magma", "plasma", "inferno", "cividis", "mako", "rocket",
    "turbo")
)

Arguments

im	A 'SpatRaster' object representing the raster data to be visualized.
scale	A numeric value that defines the vertical scale of the ridgeline plot.
palette	A character string specifying the 'viridis' color palette option to use. Available options: '"viridis"', '"magma"', '"plasma"', '"inferno"', '"cividis"', '"mako"', '"rocket"', '"turbo"'.

Details

Ridgeline plots are useful for analyzing temporal variations in raster-based satellite imagery. This function extracts raster values and visualizes their distribution across layers.

Value

A 'ggplot' object displaying the ridgeline plot.
