Create a Landscape with Diffuse Vegetation Boundary

Generates a binary landscape with a diffuse vegetation boundary where vegetation probability decreases with distance.

Usage

create_landscape_diffuse(
  width = 100,
  height = 100,
  boundary_position = 0.2,
  steepness = 0.5,
  rotation = 0
)

Arguments

width

Integer. Width of the landscape in pixels (default: 100).

height

Integer. Height of the landscape in pixels (default: 100).

boundary_position

Numeric. Relative position of vegetation boundary from top (0-1) (default: 0.5).

steepness

Numeric. Controls the transition gradient (0-1). Lower values (e.g., 0.1) create sharper transitions. Higher values (e.g., 0.9) create more gradual, diffuse transitions where vegetation probability persists further below the vegetation boundary (default: 0.5).

rotation

Numeric. Angle to rotate landscape in degrees (default: 0).

Value

A landscape object with pattern "diffuse" containing:

data

SpatRaster with binary values (0 = bare ground, 1 = vegetation)

pattern

Character string "diffuse"

params

List of all input parameters used to generate the landscape

Examples

# Default diffuse vegetation boundary
diffuse_default <- create_landscape_diffuse()

# Sharp transition (lower steepness)
diffuse_sharp <- create_landscape_diffuse(
  boundary_position = 0.2,
  steepness = 0.1
)

# Gradual transition (higher steepness)
diffuse_gradual <- create_landscape_diffuse(
  boundary_position = 0.3,
  steepness = 0.9
)

# With rotation
diffuse_rotated <- create_landscape_diffuse(
  boundary_position = 0.3,
  steepness = 0.7,
  rotation = 45
)
