Create patches for a specific feature — create

This function takes a feature and splits it into multiple "patches" of the feature. This is ideal for features that you want to protect x% of, but want to make sure that entire patches (as opposed to pieces of patches) are protected to meet that target.

Usage

create_patches(feature, spatial_grid = NULL)

Arguments

feature: a raster or sf object with the feature of interest present (value = 1) or absent (value = NA)
spatial_grid: a raster or sf template with the desired resolution and coordinate reference system generated; values in areas of interest are 1, while all other values are NA (only required if feature is a sf object)

Value

A raster or sf object with independent layers (raster)/columns (sf) designating the location of each patch

Examples

# Import some planning data
#import seamounts
seamounts <- terra::rast(system.file("extdata/seamounts.tif", package = "patchwise"))

terra::plot(seamounts)


# Create seamount patches as multi-layer raster
patches_raster <- create_patches(seamounts)
terra::plot(patches_raster)
