the number of disjunct core area(vector data)

This function allows you to calculate the number of disjunct core areas of all patches Core area is defined as an area that within the patch and its edge is a fixed value from the boundary of the patch. Disjunct core area is defined as a new discrete area(patch), which is a sub-part of core area

vm_p_ncore(landscape, class_col = NULL, patch_col = NULL, edge_depth)

Arguments

landscape

the input landscape image,

class_col

the name of the class column of the input landscape

patch_col

the name of the id column of the input landscape

edge_depth

the fixed distance to the edge of the patch

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.

Examples
