returns loaded data as a spatial object.

Usage

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

Arguments

scale

The 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

A string determining the spatial object to return. Either "sf" for for simple feature (from `sf`, the default) or "sv" for a `SpatVector` (from `terra`).

Value

An object of class `sf` for simple feature (from `sf`, the default) or `SpatVector` (from `terra`).

Details

This function should be used after first downloading the data with ne_download(load = FALSE). The downloaded file can then be loaded using this function.

# for raster download & load

# load after having downloaded
