mapSpain <img src="man/figures/logo.png" align="right" width="120"/>

mapSpain is a package that provides spatial sf objects of the administrative boundaries of Spain, including CCAA, provinces and municipalities.

mapSpain also provides a leaflet plugin to be used with the leaflet package, that loads several base maps of public institutions of Spain, and the ability of downloading and processing static tiles.

Installation

Install mapSpain from CRAN:

install.packages("mapSpain", dependencies = TRUE)

You can install the developing version of mapSpain using the r-universe:

# Install mapSpain in R:
install.packages("mapSpain",
  repos = c(
    "https://ropenspain.r-universe.dev",
    "https://cloud.r-project.org"
  ),
  dependencies = TRUE
)

Alternatively, you can install the developing version of mapSpain with:

remotes::install_github("rOpenSpain/mapSpain", dependencies = TRUE)

Usage

This script highlights some features of mapSpain :

library(mapSpain)
library(sf)
library(dplyr)
census <- mapSpain::pobmun19

# Extract CCAA from base dataset

codelist <- mapSpain::esp_codelist %>%
  select(cpro, codauto) %>%
  distinct()

census_ccaa <- census %>%
  left_join(codelist) %>%
  # Summarize by CCAA
  group_by(codauto) %>%
  summarise(pob19 = sum(pob19), men = sum(men), women = sum(women)) %>%
  mutate(
    porc_women = women / pob19,
    porc_women_lab = paste0(round(100 * porc_women, 2), "%")
  )


# Merge into spatial data

ccaa_sf <- esp_get_ccaa() %>%
  left_join(census_ccaa)
can <- esp_get_can_box()


# Plot with ggplot
library(ggplot2)


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 = scales::label_percent(),
    guide = guide_legend(title = "Porc. women", position = "inside")
  ) +
  theme_void() +
  theme(legend.position.inside = c(0.1, 0.6))

You can combine sf objects with static tiles

# Get census
census <- mapSpain::pobmun19 %>%
  mutate(porc_women = women / pob19) %>%
  select(cpro, cmun, porc_women)

# Get shapes
shape <- esp_get_munic_siane(region = "Segovia", epsg = 3857)
provs <- esp_get_prov_siane(epsg = 3857)

shape_pop <- shape %>% left_join(census)


tile <- esp_getTiles(shape_pop, type = "IGNBase.Todo", zoommin = 1)

# Plot

library(ggplot2)
library(tidyterra)

lims <- as.vector(terra::ext(tile))

ggplot(remove_missing(shape_pop, na.rm = TRUE)) +
  geom_spatraster_rgb(data = tile, maxcell = 10e6) +
  geom_sf(aes(fill = porc_women), color = NA) +
  geom_sf(data = provs, fill = NA) +
  scale_fill_gradientn(
    colours = hcl.colors(10, "RdYlBu", alpha = .5),
    n.breaks = 8,
    labels = function(x) {
      sprintf("%1.0f%%", 100 * x)
    },
    guide = guide_legend(title = "", )
  ) +
  coord_sf(
    xlim = lims[c(1, 2)],
    ylim = lims[c(3, 4)],
    expand = FALSE
  ) +
  labs(
    title = "Share of women in Segovia by town (2019)",
    caption = "Source: INE"
  ) +
  theme_void() +
  theme(
    title = element_text(face = "bold")
  )

mapSpain and giscoR

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)

library(ggplot2)

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")
  )

A note on caching

Some data sets and tiles may have a size larger than 50MB. You can use mapSpain to create your own local repository at a given local directory passing the following option:

esp_set_cache_dir("./path/to/location")

When this option is set, mapSpain would look for the cached file and it will load it, speeding up the process.

Plotting sf objects

Some packages recommended for visualization are:

• tmap
• mapsf
• ggplot2 + tidyterra.
• leaflet
