rnaturalearth

An R package to hold and facilitate interaction with Natural Earth map data.

This package provides :

The Natural Earth website structures vector data by scale, category and type. These determine the filenames of downloads. rnaturalearth uses this structure to facilitate download (like an API).

Install rnaturalearth

Install from CRAN :

install.packages("rnaturalearth")

or install the development version from GitHub using devtools.

devtools::install_github("ropensci/rnaturalearth")

Data to support much of the package functionality are stored in two data packages that you will be prompted to install when required if you do not do so here.

devtools::install_github("ropensci/rnaturalearthdata")
devtools::install_github("ropensci/rnaturalearthhires")

First usage

Here using plot as a simple, quick way to plot maps. Maps could also be made with ggplot2, tmap or other options. All retrieval functions accept an argument returnclass = "sf" to return package sf (Simple Features) or returnclass = "sv" (SpatVector) objects.

library(rnaturalearth)

# world countries
plot(ne_countries())
Warning: plotting the first 9 out of 168 attributes; use max.plot = 168 to plot
all


# uk
plot(ne_countries(country = "united kingdom"))
Warning: plotting the first 10 out of 168 attributes; use max.plot = 168 to
plot all


# states, admin level1 boundaries
plot(ne_states(country = "spain"))
Warning: plotting the first 9 out of 121 attributes; use max.plot = 121 to plot
all

To download Natural Earth data not already in the package

There are a wealth of other data available at the Natural Earth website. rnaturalearth has functions to help with download of these data.

The data available are outlined in the two tables below and online here.


category   cultural 

category   physical 

Specify the scale, category and type of the vector you want as in the examples below.

# lakes
lakes110 <- ne_download(scale = 110, type = "lakes", category = "physical")
plot(lakes110)

# rivers
rivers50 <- ne_download(
  scale = 50,
  type = "rivers_lake_centerlines",
  category = "physical",
  returnclass = "sf"
)

library(ggplot2)
library(sf)

ggplot(rivers50) +
  geom_sf() +
  theme_minimal()
