Plot elevation data as ridgelines — plot

Creates topographical elevation ridgeline plots, inspired by the iconic Joy Division album cover.

Usage

plot_ridgelines(
  elevation = NULL,
  n_lines = 30,
  scale_factor = 10,
  line_color = "white",
  fill_color = "#FFFFFF1A",
  linewidth = 0.5,
  background_color = "black"
)

Arguments

elevation: A raster object containing elevation data, as returned by get_elevation()
n_lines: Number of ridgelines to draw (default: 30). More lines create a denser visualization but may increase plotting time.
scale_factor: Scaling factor for the height of ridgelines (default: 10). Higher values make the elevation differences more pronounced.
line_color: Color of the ridgelines (default: "white")
fill_color: Fill color below the lines (default: "#FFFFFF1A", semi-transparent white)
linewidth: Width of the ridgelines (default: 0.5)
background_color: Background color of the plot (default: "black")

Value

A ggplot object that can be further customized using ggplot2 functions

Examples

# Default style (white on black)
plot_ridgelines(ele_wilder_kaiser)


# No fill, just lines
plot_ridgelines(
  ele_wilder_kaiser,
  fill_color = NA,
  scale_factor = 12
)


# Classic black on white style
plot_ridgelines(
  ele_wilder_kaiser,
  line_color = "#000000",
  fill_color = "white",
  background_color = "white",
  scale_factor = 8
)


# Get creative!
plot_ridgelines(
  ele_wilder_kaiser,
  n_lines = 35,
  line_color = "#FF4081",
  fill_color = "#FF408133",
  background_color = "#1A237E"
)
