esp_get_munic_siane: Municipalities of Spain from SIANE

In mapSpain: Administrative Boundaries and Static Map Tiles for Spain

Municipalities of Spain from SIANE

Description

Get boundaries of municipalities in Spain.

Usage

esp_get_munic_siane(
  year = Sys.Date(),
  epsg = 4258,
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  resolution = c(3, 6.5, 10),
  region = NULL,
  munic = NULL,
  moveCAN = TRUE,
  rawcols = FALSE
)

Arguments

year	Character string or number. Release year. It must use format YYYY (assuming end of year) or YYYY-MM-DD. Historical information starts as of 2005.
epsg	Character string or number. Projection of the map: 4-digit EPSG code. One of: "4258": ETRS89. "4326": WGS84. "3035": ETRS89 / ETRS-LAEA. "3857": Pseudo-Mercator.
cache	Logical. Whether to cache downloaded files. Defaults to TRUE. See Caching.
update_cache	Logical. If TRUE, refreshes the cached file and forces a new download. Defaults to FALSE.
cache_dir	Character string. A path to a cache directory. See Caching.
verbose	A logical value indicating whether to display informational messages.
resolution	Character string or number. Resolution of the geospatial data. One of: "10": 1:10 million. "6.5": 1:6.5 million. "3": 1:3 million.
region	Optional. A vector of region names, NUTS or ISO codes (see esp_dict_region_code()).
munic	Character string. A name or regex expression with the names of the required municipalities. Use NULL to return all municipalities.
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 in esp_move_can().
rawcols	Logical. If TRUE, retains the raw columns of the resulting object as provided by IGN.

Details

When using region 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).

When calling a higher level, such as a province, Autonomous Community, Autonomous City or NUTS 1 region, all municipalities of that level are added.

Value

A sf object.

Caching

Functions that download data store files in cache_dir. When cache_dir is NULL, they use the active package cache, which defaults to a temporary directory. Set update_cache = TRUE to replace an existing cached file. See Caching strategies in esp_set_cache_dir() to configure a persistent cache.

Note

Although mapSpain supplies cartographically suitable datasets, a historical database of Spanish municipal boundaries is also available, offering higher-resolution geometries that may be more appropriate for GIS-oriented workflows:
