Fullness Index(vector data) — vm_c_fullness • vectormetrics

Calculate Fullness Index

vm_c_fullness(landscape, class_col, n = 1000)

Arguments

landscape: the input landscape image,
class_col: the name of the class column of the input landscape
n: number of local neighbourhoods to consider in calculating fullness

Value

the function returns tibble with the calculated values in column "value", this function returns also some important information such as level, class, patch id and metric name.

Details

ratio between the average fullness of small neighbourhoods (1
