esp_get_nuts: Get NUTS of Spain as `sf` polygons and points

Description

Returns NUTS regions of Spain as polygons and points at a specified scale, as provided by GISCO (Geographic Information System of the Commission, depending of Eurostat).

NUTS are provided at three different levels:

"0": Country level
"1": Groups of autonomous communities
"2": Autonomous communities
"3": Roughly matches the provinces, but providing specific individual objects for each major island

Usage

esp_get_nuts(
  year = "2016",
  epsg = "4258",
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  resolution = "01",
  spatialtype = "RG",
  region = NULL,
  nuts_level = "all",
  moveCAN = TRUE
)

Arguments

year

Release year of the file. One of "2003", "2006", "2010", "2013", "2016" or "2021".

epsg

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

"4258": ETRS89
"4326": WGS84
"3035": ETRS89 / ETRS-LAEA
"3857": Pseudo-Mercator

cache

A logical whether to do caching. Default is TRUE. See About caching.

update_cache

A logical whether to update cache. Default is FALSE. When set to TRUE it would force a fresh download of the source file.

cache_dir

A path to a cache directory. See About caching.

verbose

Logical, displays information. Useful for debugging, default is FALSE.

resolution

Resolution of the geospatial data. One of

"60": 1:60million
"20": 1:20million
"10": 1:10million
"03": 1:3million
"01": 1:1million

spatialtype

Type of geometry to be returned:

"LB": Labels - point object.
"RG": Regions - polygon object.

region

Optional. A vector of region names, NUTS or ISO codes (see esp_dict_region_code()).

nuts_level

NUTS level. One of "0" (Country-level), "1", "2" or "3". See Description.

moveCAN

A logical TRUE/FALSE or a vector of coordinates c(lat, lon). It places the Canary Islands close to Spain's mainland. Initial position can be adjusted using the vector of coordinates. See Displacing the Canary Islands.

Value

A sf object specified by spatialtype.

About caching

You can set your cache_dir with esp_set_cache_dir().

Sometimes cached files may be corrupt. On that case, try re-downloading the data setting update_cache = TRUE.

If you experience any problem on download, try to download the corresponding .geojson file by any other method and save it on your cache_dir. Use the option verbose = TRUE for debugging the API query.

Displacing the Canary Islands

While moveCAN is useful for visualization, it would alter the actual geographic position of the Canary Islands. When using the output for spatial analysis or using tiles (e.g. with esp_getTiles() or addProviderEspTiles()) this option should be set to FALSE in order to get the actual coordinates, instead of the modified ones.

Examples

Run this code

# NOT RUN {
NUTS1 <- esp_get_nuts(nuts_level = 1, moveCAN = TRUE)

library(ggplot2)

ggplot(NUTS1) +
  geom_sf() +
  labs(
    title = "NUTS1: Displacing Canary Islands",
    caption = giscoR::gisco_attributions()
  )


NUTS1_alt <- esp_get_nuts(nuts_level = 1, moveCAN = c(15, 0))


ggplot(NUTS1_alt) +
  geom_sf() +
  labs(
    title = "NUTS1: Displacing Canary Islands",
    subtitle = "to the right",
    caption = giscoR::gisco_attributions()
  )


NUTS1_orig <- esp_get_nuts(nuts_level = 1, moveCAN = FALSE)

ggplot(NUTS1_orig) +
  geom_sf() +
  labs(
    title = "NUTS1",
    subtitle = "Canary Islands on the true location",
    caption = giscoR::gisco_attributions()
  )


AndOriental <-
  esp_get_nuts(region = c("Almeria", "Granada", "Jaen", "Malaga"))


ggplot(AndOriental) +
  geom_sf()



RandomRegions <- esp_get_nuts(region = c("ES1", "ES300", "ES51"))

ggplot(RandomRegions) +
  geom_sf() +
  labs(title = "Random Regions")


MixingCodes <- esp_get_nuts(region = c("ES4", "ES-PV", "Valencia"))


ggplot(MixingCodes) +
  geom_sf() +
  labs(title = "Mixing Codes")
# }
