esp_get_prov: Get Provinces of Spain as sf polygons and points

Description

Returns provinces of Spain as polygons and points at a specified scale.

• esp_get_prov() uses GISCO (Eurostat) as source. Please use giscoR::gisco_attributions()

• esp_get_prov_siane() uses CartoBase ANE as source, provided by Instituto Geografico Nacional (IGN), http://www.ign.es/web/ign/portal. Years available are 2005 up to today.

Usage

esp_get_prov(prov = NULL, ...)
esp_get_prov_siane(
  prov = NULL,
  year = Sys.Date(),
  epsg = "4258",
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  resolution = "3",
  moveCAN = TRUE,
  rawcols = FALSE
)

Arguments

prov

A vector of names and/or codes for provinces or NULL to get all the provinces. See Details.

...

Arguments passed on to esp_get_nuts

spatialtype

Type of geometry to be returned:

• "LB": Labels - point object.

• "RG": Regions - polygon object.

year

Release year. See esp_get_nuts() for esp_get_prov() and Details for esp_get_prov_siane()

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 polygon. Values available are "3", "6.5" or "10".

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.

rawcols

Logical. Setting this to TRUE would add the raw columns of the dataset provided by IGN.

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.

Details

When using prov you can use and mix names and NUTS codes (levels 1, 2 or 3), ISO codes (corresponding to level 2 or 3) or "cpro" (see esp_codelist).

Ceuta and Melilla are considered as provinces on this dataset.

When calling a superior level (Autonomous Community or NUTS1) , all the provinces of that level would be added.

On esp_get_prov_siane(), year could be passed as a single year ("YYYY" format, as end of year) or as a specific date ("YYYY-MM-DD" format). Historical information starts as of 2005.
