Plot a SamsaRaLight virtual stand

Source: R/plot.sl_stand.R
plot.sl_stand.Rd

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.

Value

A ggplot object representing the stand.

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)
