mapSpain is a package designed to provide geographical information of Spain at different levels.
mapSpain provides shapefiles of municipalities, provinces, autonomous communities and NUTS levels of Spain. It also provides hexbin shapefiles and other complementary shapes, as the usual lines around the Canary Islands.
mapSpain provides access to map tiles of public
organisms of Spain, that can be represented on static maps via
mapSpain::esp_getTiles() or on a R
leaflet map using
mapSpain::addProviderEspTiles().
On top of that, mapSpain also has a powerful dictionary that translate provinces and other regions to English, Spanish, Catalan, Basque language or Galician, and also converts those names to different coding standards, as NUTS, ISO2 or the coding system used by the INE, that is the official statistic agency of Spain.
mapSpain provides a dataset and tile caching capability, that could be set as:
mapSpain relies on giscoR for downloading some files, and both packages are well synchronized. Setting the same caching directory on both would speed up the data load on your session.
Some examples of what mapSpain can do:
library(mapSpain)
library(ggplot2)
country <- esp_get_country()
lines <- esp_get_can_box()
ggplot(country) +
geom_sf(fill = "cornsilk", color = "#887e6a") +
labs(title = "Map of Spain") +
theme(
panel.background = element_rect(fill = "#fffff3"),
panel.border = element_rect(
colour = "#887e6a",
fill = NA,
),
text = element_text(
family = "serif",
face = "bold"
)
)
Example: Map of Spain
# Plot provinces
Andalucia <- esp_get_prov("Andalucia")
ggplot(Andalucia) +
geom_sf(fill = "darkgreen", color = "white") +
theme_bw()
Example: Provinces of Andalucia
# Plot municipalities
Euskadi_CCAA <- esp_get_ccaa("Euskadi")
Euskadi <- esp_get_munic(region = "Euskadi")
# Use dictionary
Euskadi$name_eu <- esp_dict_translate(Euskadi$ine.prov.name, lang = "eu")
ggplot(Euskadi_CCAA) +
geom_sf(fill = "grey50") +
geom_sf(data = Euskadi, aes(fill = name_eu)) +
scale_fill_manual(values = c("red2", "darkgreen", "ivory2")) +
labs(
fill = "",
title = "Euskal Autonomia Erkidegoko",
subtitle = "Probintziak"
) +
theme_void() +
theme(
plot.title = element_text(face = "bold"),
plot.subtitle = element_text(face = "italic")
)
Example: Municipalities of the Basque Country
Let’s analyze the distribution of women in each autonomous community
with ggplot:
census <- mapSpain::pobmun19
# Extract CCAA from base dataset
codelist <- mapSpain::esp_codelist
census <- unique(merge(census, codelist[, c("cpro", "codauto")], all.x = TRUE))
# Summarize by CCAA
census_ccaa <- aggregate(cbind(pob19, men, women) ~ codauto, data = census, sum)
census_ccaa$porc_women <- census_ccaa$women / census_ccaa$pob19
census_ccaa$porc_women_lab <- paste0(
round(100 * census_ccaa$porc_women, 2),
"%"
)
# Merge into spatial data
CCAA_sf <- esp_get_ccaa()
CCAA_sf <- merge(CCAA_sf, census_ccaa)
Can <- esp_get_can_box()
ggplot(CCAA_sf) +
geom_sf(aes(fill = porc_women),
color = "grey70",
linewidth = .3
) +
geom_sf(data = Can, color = "grey70") +
geom_sf_label(aes(label = porc_women_lab),
fill = "white", alpha = 0.5, size = 3, label.size = 0
) +
scale_fill_gradientn(
colors = hcl.colors(10, "Blues", rev = TRUE),
n.breaks = 10,
labels = function(x) {
sprintf("%1.1f%%", 100 * x)
},
guide = guide_legend(title = "Porc. women", position = "inside")
) +
theme_void() +
theme(legend.position.inside = c(0.1, 0.6))
Percentage of women by Autonomous Community (2019)
This is an example on how mapSpain can be used to
beautiful thematic maps. For plotting purposes we would use the ggplot
package, however any package that handles sf objects
(e.g. tmap, mapsf,
leaflet, etc. could be used).
# Population density of Spain
library(sf)
pop <- mapSpain::pobmun19
munic <- esp_get_munic()
# Get area (km2) - Use LAEA projection
municarea <- as.double(st_area(st_transform(munic, 3035)) / 1000000)
munic$area <- municarea
munic.pop <- merge(munic, pop, all.x = TRUE, by = c("cpro", "cmun"))
munic.pop$dens <- munic.pop$pob19 / munic.pop$area
br <- c(-Inf, 10, 25, 100, 200, 500, 1000, 5000, 10000, Inf)
munic.pop$cuts <- cut(munic.pop$dens, br)
ggplot(munic.pop) +
geom_sf(aes(fill = cuts), color = NA, linewidth = 0) +
scale_fill_manual(
values = c("grey5", hcl.colors(length(br) - 2, "Spectral")),
labels = prettyNum(c(0, br[-1]), big.mark = ","),
guide = guide_legend(title = "Pop. per km2", direction = "horizontal", nrow = 1)
) +
labs(title = "Population density in Spain (2019)") +
theme_void() +
theme(
plot.title = element_text(hjust = .5),
plot.background = element_rect(fill = "black"),
text = element_text(colour = "white"),
legend.position = "bottom",
legend.title.position = "top",
legend.text.position = "bottom",
legend.key.width = unit(30, "pt")
)
Population density in Spain (2019)
If you need to plot Spain along with another countries, consider using giscoR package, that is installed as a dependency when you installed mapSpain. A basic example:
library(giscoR)
# Set the same resolution for a perfect fit
res <- "20"
all_countries <- gisco_get_countries(resolution = res) |>
st_transform(3035)
eu_countries <- gisco_get_countries(
resolution = res, region = "EU"
) |>
st_transform(3035)
ccaa <- esp_get_ccaa(
moveCAN = FALSE, resolution = res
) |>
st_transform(3035)
# Plot
ggplot(all_countries) +
geom_sf(fill = "#DFDFDF", color = "#656565") +
geom_sf(data = eu_countries, fill = "#FDFBEA", color = "#656565") +
geom_sf(data = ccaa, fill = "#C12838", color = "grey80", linewidth = .1) +
# Center in Europe: EPSG 3035
coord_sf(
xlim = c(2377294, 7453440),
ylim = c(1313597, 5628510)
) +
theme(
panel.background = element_blank(),
panel.grid = element_line(
colour = "#DFDFDF",
linetype = "dotted"
)
)
mapSpain and giscoR example
mapSpain provides a powerful interface for working
with imagery. mapSpain can download static files as
.png orjpeg files (depending on the Web Map
Service) and use them along your shapefiles.
mapSpain also includes a plugin for R leaflet package, that allows you to include several basemaps on your interactive maps.
The services are implemented via the leaflet plugin leaflet-providersESP. You can check a display of each provider on the previous link.
Note that When working with imagery, it is important
to set moveCAN = FALSE on the esp_get_*
functions. See Displacing the Canary Islands on
help("esp_get_ccaa", package = "mapSpain").
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
