rasterizeRange: Rasterize Species Data from Shapefile

In RS-eco/rasterSp: R Package to rasterize and summarise IUCN range maps

Rasterize Species Data from Shapefile

Description

Rasterize shapefile of multiple polygons to individual global rasters with a specific resolution

Usage

rasterizeRange(
  dsn = paste0(getwd(), "/IUCN/AMPHIBIANS.shp"),
  id = "binomial",
  resolution = 0.5,
  save = TRUE,
  touches = TRUE,
  extent = c(-180, 180, -90, 90),
  split = NA,
  name_split = c(1, 2),
  seasonal = NA,
  origin = NA,
  presence = NA,
  getCover = F,
  df = F,
  crs = "+proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0",
  path = getwd()
)

Arguments

dsn	Path to one shapefile with multiple polygons or a list of files
id	character Character specifying the id column
resolution	integer Resolution in degrees
save	logical Should individual output be stored. Path to output folder can be specified under path
touches	logical If TRUE, all cells touched by lines or polygons are affected, not just those on the line render path, or whose center point is within the polygon.
extent	extent Extent of area that we are interested in.
split	character default is NA
name_split	integer Specifies which splits to use, default is c(1,2).
seasonal	integer 1 = Resident, 2 = Breeding Season, 3 = Non-breeding Season, 4 = Passage, 5 = Seasonal occurence uncertain.
origin	integer 1 = Native, 2 = Reintroduced, 3 = Introduced, 4 = Vagrant, 5 = Origin Uncertain.
presence	integer 1 = Extant, 2 = Probably Extant, 3 = Possibly Extant, 4 = Possibly Extinct, 5 = Extinct (post 1500), 6 = Presence Uncertain.
getCover	logical Calculate the percentage covered by a polygon rather than the presence of a species
df	logical Store the output as data.frame or not. If df=FALSE output will be stored as .tif files.
crs	character Define the output projection of your data.
path	character Path where individual output files are going to be stored.

Value

list of raster layers for each id with the given area shapefile
