generate_stand_from_trees: Generate stem maps from tables of individual trees

In mikemahoney218/forthetrees: What the Package Does (One Line, Title Case)

Generate stem maps from tables of individual trees

Description

This function simulates stem maps for stands, basing density and attributes on tree measurements provided to data.

Usage

generate_stand_from_trees(
  data,
  stand_area,
  ...,
  measured_area,
  cols = dplyr::everything()
)

Arguments

data	The data.frame
stand_area	sf object: The polygon to simulate trees within. Sampling is perfomed using sf::st_sample().
...	Passed to sf::st_sample().
measured_area	Either numeric (the total amount of area represented by data) of sf object (representing the measurement boundary). Used to calculate
cols	Names of columns to simulate for each new tree

Value

An sf object, representing new tree positions in the stem map, with simulated variables.

Examples

stand_area <- sf::st_bbox(c(xmin = 0, ymin = 0, xmax = 140, ymax = 140))
stand_area <- sf::st_as_sfc(stand_area)

measured_area <- 19600

trees <- tree_positions[c("SPECIES", "DBH85")]
trees$SPECIES <- factor(trees$SPECIES)

generate_stand_from_trees(
  trees,
  stand_area,
  measured_area = measured_area
)
