Prepare habitat and barrier rasters

Convert vector (shapefile) SF habitat and barrier objects into rasters.

Usage

prepare_rasters(
  habitat,
  barrier,
  data_resolution = 10,
  target_resolution = 500
)

Arguments

habitat

SF object. Habitat spatial data.

barrier

SF object. Barrier spatial data.

data_resolution

Numeric. Fine resolution in meters. Default, 10.

target_resolution

Numeric. Coarse resolution in meters. Default, 500.

Value

List with habitat_raster and barrier_raster elements.
