gisco_get_countries: Download Geospatial Country Data from GISCO

Description

Downloads a simple feature (sf) object.

Usage

gisco_get_countries(
  resolution = "20",
  year = "2016",
  epsg = "4326",
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  spatialtype = "RG",
  country = NULL,
  region = NULL
)

Arguments

resolution

Resolution of the geospatial data. One of

• "60" (1:60million),

• "20" (1:20million)

• "10" (1:10million)

• "03" (1:3million) or

• "01" (1:1million).

year

Release year. One of "2001", "2006", "2010", "2013", "2016" or "2020"

epsg

projection of the map: 4-digit EPSG code. One of:

• "4326" - WGS84

• "3035" - ETRS89 / ETRS-LAEA

• "3857" - Pseudo-Mercator

cache

a logical whether to do caching. Default is TRUE.

spatialtype

Type of geometry to be returned:

• RG: Regions - Multipolygon

• LB: Labels - Point

• BN: Boundaries - Multilines

• COASTL: coastlines - Multilines

• INLAND: inland boundaries - Multilines

country

Optional. A character vector of countries. See Details

region

Optional. A character vector of UN M49 region codes. Possible values are "Africa", "Americas", "Asia", "Europe", "Oceania". See Details and gisco_countrycode
