plot.sl_stand: Plot a SamsaRaLight virtual stand

In SamsaRaLight: Simulate Tree Light Transmission Using Ray-Tracing

Plot a SamsaRaLight virtual stand

Description

This function plots a virtual forest stand (sl_stand) produced by SamsaRaLight. It can display a top-down view with tree crowns or a side/top view with cells and trees.

Usage

## S3 method for class 'sl_stand'
plot(x, ..., top_down = FALSE, only_inv = FALSE, add_sensors = TRUE)

Arguments

x	An object of class sl_stand.
...	Additional arguments passed to lower-level plotting functions.
top_down	Logical, if TRUE, creates a top-down view with multiple directions (south, north, west, east).
only_inv	Logical, if TRUE, plot only trees from the initial inventory (i.e. not trees added to fill around the core polygon)
add_sensors	Logical; if TRUE (default), sensors are drawn on the plot. In top-down mode, sensors are shown as segment from ground to their height; in map view, sensors are drawn as squares on the ground.

Details

For the sake of the representation in top-down plot, z are offset such as minimum altitude tree is at Y-axis height = 0

The plot function also generates a compass indicating:

• Plot orientation (north2x, north in red)

• Terrain aspect (downslope direction)

• Slope degrees (annotation only)

Value

A ggplot object representing the stand.
