Plot a from-above view of a tree inventory

Visualizes a forest inventory as ellipses representing tree crowns.

Usage

plot_inventory(trees_inv, core_polygon_df = NULL, show_id = TRUE)

Arguments

trees_inv

A data.frame of trees that passed check_inventory.

core_polygon_df

Optional data.frame defining the core inventory polygon. Must contain columns x and y.

show_id

Logical; if TRUE (default), displays tree identifiers at crown centers.

Details

Because the north2x variable is unknown, trees are plotted as circles by considering the mean radius on the four cardinals.
