get_circumscribingcircle: get_circumscribingcircle

Description

Diameter of the circumscribing circle around patches

Usage

get_circumscribingcircle(landscape, directions, level)
# S3 method for RasterLayer
get_circumscribingcircle(landscape, directions = 8, level = "patch")
# S3 method for RasterStack
get_circumscribingcircle(landscape, directions = 8, level = "patch")
# S3 method for RasterBrick
get_circumscribingcircle(landscape, directions = 8, level = "patch")
# S3 method for stars
get_circumscribingcircle(landscape, directions = 8, level = "patch")
# S3 method for list
get_circumscribingcircle(landscape, directions = 8, level = "patch")

Arguments

landscape

RasterLayer or matrix (with x, y, id columns)

directions

The number of directions in which patches should be connected: 4 (rook's case) or 8 (queen's case).

level

Either 'patch' or 'class' for the corresponding level.

Details

The diameter of the smallest circumscribing circle around a patch in the landscape is based on the maximum distance between the corners of each cell. This ensures that all cells of the patch are included in the patch.
