get_centroids function

get_centroids

Centroid of patches

get_centroids(
  landscape,
  directions = 8,
  cell_center = FALSE,
  return_vec = FALSE,
  verbose = TRUE
)

Arguments

• landscape: A categorical raster object: SpatRaster; Raster* Layer, Stack, Brick; stars or a list of SpatRasters.
• directions: The number of directions in which patches should be connected: 4 (rook's case) or 8 (queen's case).
• cell_center: If true, the coordinates of the centroid are forced to be a cell center within the patch.
• return_vec: If true, a sf object is returned.
• verbose: Print warning messages

Details

Get the coordinates of the centroid of each patch. The centroid is by default defined as the mean location of all cell centers. To force the centroid to be located within each patch, use the cell_center argument. In this case, the centroid is defined as the cell center that is the closest to the mean location.

Examples

# get centroid location
landscape <- terra::rast(landscapemetrics::landscape)
get_centroids(landscape)
