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 sp::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) objects.

library(rnaturalearth)
The legacy packages maptools, rgdal, and rgeos, underpinning the sp package,
which was just loaded, will retire in October 2023.
Please refer to R-spatial evolution reports for details, especially
https://r-spatial.org/r/2023/05/15/evolution4.html.
It may be desirable to make the sf package available;
package maintainers should consider adding sf to Suggests:.
The sp package is now running under evolution status 2
     (status 2 uses the sf package in place of rgdal)
Support for Spatial objects (`sp`) will be deprecated in {rnaturalearth} and will be removed in a future release of the package. Please use `sf` objects with {rnaturalearth}. For example: `ne_download(returnclass = 'sf')`
library(sp)

# world countries
sp::plot(ne_countries())
Warning: The `returnclass` argument of `ne_download()` sp as of rnaturalearth 1.0.0.
ℹ Please use `sf` objects with {rnaturalearth}, support for Spatial objects
  (sp) will be removed in a future release of the package.
This warning is displayed once every 8 hours.
Call `lifecycle::last_lifecycle_warnings()` to see where this warning was
generated.

# uk
sp::plot(ne_countries(country = "united kingdom"))

# states, admin level1 boundaries
sp::plot(ne_states(country = "spain"))

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")
sp::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()
