  country = NULL,
  unnamed_streets = TRUE,

  streets_sf = NULL,
  country_code_type = "eurostat",
  year = 2021,
  fallback = TRUE
)

Arguments

gisco_id

Gisco identifier.

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().

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().

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

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

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