ll_osm_get_lau_streets(
  gisco_id,
  country = NULL,
  unnamed_streets = TRUE,
  lau_boundary_sf = NULL,
  streets_sf = NULL,
  country_code_type = "eurostat",
  year = 2021,
  fallback = TRUE
)

Arguments

gisco_id

Gisco identifier.

country

Name of country as included in Geofabrik's datasets, does not always match common country names or geography. For details on available country names see the dataset included in this package: ll_osm_countries

unnamed_streets

Defaults to TRUE. If FALSE, it drops all streets with missing "name" or missing "fclass".

lau_boundary_sf

Defaults to NULL. If given, used to speed up processing. Must be an sf object such as the ones output by by ll_get_lau_eu().

streets_sf

Defaults to NULL. If given, used to speed up processing. Must be an sf object such as the ones output by ll_osm_get_roads().

country_code_type

Defaults to "eurostat". An alternative common value is "iso2c". See countrycode::codelist for a list of available codes.

year

Year of LAU boundaries, defaults to most recent (2021), passed to ll_get_lau_eu(). Available starting with 2011.

fallback

Logical, defaults to TRUE. If a gisco_id does not match an entity in ll_get_lau_eu(), try alternatives for the boundaries based on the country code, including ll_get_nuts_eu(), ll_get_gadm(), and ll_get_adm_ocha().

Value

An sf objects with all streets of a given LAU based on OpenStreetMap

Examples

if (FALSE) { # \dontrun{
ll_osm_get_lau_streets(gisco_id = "IT_022205", unnamed_streets = FALSE)

# or if country name does not match

ll_osm_get_lau_streets(gisco_id = "EL_01020204", country = "greece")
} # }
