Source: R/ne_load.R
ne_load.Rd

returns loaded data as a spatial object.

Usage

ne_load(
  scale = 110,
  type = "countries",
  category = c("cultural", "physical", "raster"),
  destdir = tempdir(),
  file_name = NULL,
  returnclass = c("sp", "sf")
)

Arguments

scale

scale of map to return, one of 110, 50, 10 or 'small', 'medium', 'large'

type

type of natural earth file one of 'countries', 'map_units', 'map_subunits', 'sovereignty', 'states' OR the portion of any natural earth vector url after the scale and before the . e.g. for 'ne_50m_urban_areas.zip' this would be 'urban_areas' OR the raster filename e.g. for 'MSR_50M.zip' this would be 'MSR_50M'

category

one of natural earth categories : 'cultural', 'physical', 'raster'

destdir

folder to load files from, default=tempdir()

file_name

OPTIONAL name of file (excluding path) instead of natural earth attributes

returnclass

'sp' default or 'sf' for Simple Features

Value

A Spatial object depending on the data (points, lines, polygons or raster).

Examples

if (FALSE) {
# download followed by load from tempdir() works in same R session
spdf_world <- ne_download(scale = 110, type = "countries")
spdf_world2 <- ne_load(scale = 110, type = "countries")

# download followed by load from specified directory works between R sessions
spdf_world <- ne_download(scale = 110, type = "countries", destdir = getwd())
spdf_world2 <- ne_load(scale = 110, type = "countries", destdir = getwd())

# for raster download & load
rst <- ne_download(scale = 50, type = "OB_50M", category = "raster", destdir = getwd())

# load after having downloaded
rst <- ne_load(scale = 50, type = "OB_50M", category = "raster", destdir = getwd())

# plot
library(terra)
plot(rst)
# end dontrun
