Urban Audit dataset

Source: R/gisco-get-urban-audit.R
gisco_get_urban_audit.Rd

The dataset contains the boundaries of cities ("CITIES"), greater cities ("GREATER_CITIES") and functional urban areas ("FUA") as defined according to the EC-OECD city definition. This is used for the Eurostat Urban Audit data collection.

Please note that this function gets data from the aggregated GISCO Urban Audit file. If you prefer to download individual urban audit files, please use gisco_get_unit_urban_audit().

Usage

gisco_get_urban_audit(
  year = 2021,
  epsg = 4326,
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  spatialtype = c("RG", "LB"),
  country = NULL,
  level = c("all", "CITIES", "FUA", "GREATER_CITIES", "CITY", "KERN", "LUZ"),
  ext = "gpkg"
)

Arguments

year

character string or number. Release year of the file. One of "2021", "2020", "2018", "2014", "2004", "2001" .

epsg

character string or number. Projection of the map: 4-digit EPSG code. One of:

cache

logical. Whether to do caching. Default is TRUE. See Caching strategies section in gisco_set_cache_dir().

update_cache

logical. Should the cached file be refreshed?. Default is FALSE. When set to TRUE it would force a new download.

cache_dir

character string. A path to a cache directory. See Caching strategies section in gisco_set_cache_dir().

verbose

logical. If TRUE displays informational messages.

spatialtype

character string. Type of geometry to be returned. Options available are:

  • "RG": Regions - MULTIPOLYGON/POLYGON object.

  • "LB": Labels - POINT object.

country

character vector of country codes. It could be either a vector of country names, a vector of ISO3 country codes or a vector of Eurostat country codes. See also countrycode::countrycode().

level

character string. Level of Urban Audit. Possible values "all" (the default), that would download the full dataset or "CITIES", "FUA", and (for versions prior to year = 2020) "GREATER_CITIES", "CITY", "KERN" or "LUZ".

ext

character. Extension of the file (default "gpkg"). One of "shp", "gpkg", "geojson" .

Value

A sf object.

Details

See more in Eurostat - Statistics Explained.

The cities are defined at several conceptual levels:

  • The core city ("CITIES"), using an administrative definition.

  • The Functional Urban Area/Large Urban Zone ("FUA"), approximating the functional urban region. The coverage is the EU plus Iceland, Norway and Switzerland . The dataset includes polygon features, point features and a related attribute table which can be joined on the URAU code field.

The "URAU_CATG" field defines the Urban Audit category:

  • "C" = City.

  • "F" = Functional Urban Area Service Type.
