The total core area of the whole landscape(vector data)

This function allows you to calculate the total core area in a categorical landscape in vector data format

vm_l_tca(landscape, edge_depth)

Arguments

landscape

the input landscape image,

edge_depth

the fixed distance to the edge of the patch

Value

the returned calculated total class core areas are in column "value", and this function returns also some important information such as level and metric name, Moreover, class number and the "id" column, although both are "NA" here in the landscape level

Examples

vm_l_tca(vector_landscape, edge_depth= 1)
#> # A tibble: 1 × 5
#>   level     class id    metric  value
#>   <chr>     <chr> <chr> <chr>   <dbl>
#> 1 landscape NA    NA    tca    0.0265
