geo_amenity: Geocode amenities

In nominatimlite: Interface with 'Nominatim' API Service

Geocode amenities

Description

This function search amenities as defined by OpenStreetMap on a restricted area defined by a bounding box in the form ⁠(<xmin>, <ymin>, <xmax>, <ymax>)⁠. This function returns the tibble associated with the query, see geo_amenity_sf() for retrieving the data as a spatial object (sf format).

Usage

geo_amenity(
  bbox,
  amenity,
  lat = "lat",
  long = "lon",
  limit = 1,
  full_results = FALSE,
  return_addresses = TRUE,
  verbose = FALSE,
  nominatim_server = "https://nominatim.openstreetmap.org/",
  progressbar = TRUE,
  custom_query = list(),
  strict = FALSE
)

Arguments

bbox	The bounding box (viewbox) used to limit the search. It could be: A numeric vector of longitude (x) and latitude (y) ⁠(xmin, ymin, xmax, ymax)⁠. See Details. A sf or sfc object.
amenity	A character (or a vector of characters) with the amenities to be geolocated (i.e. c("pub", "restaurant")). See osm_amenities.
lat	Latitude column name in the output data (default "lat").
long	Longitude column name in the output data (default "long").
limit	Maximum number of results to return per input address. Note that each query returns a maximum of 50 results.
full_results	Returns all available data from the API service. If FALSE (default) only latitude, longitude and address columns are returned. See also return_addresses.
return_addresses	Return input addresses with results if TRUE.
verbose	If TRUE then detailed logs are output to the console.
nominatim_server	The URL of the Nominatim server to use. Defaults to "https://nominatim.openstreetmap.org/".
progressbar	Logical. If TRUE displays a progress bar to indicate the progress of the function.
custom_query	A named list with API-specific parameters to be used (i.e. list(countrycodes = "US")). See Details.
strict	Logical TRUE/FALSE. Force the results to be included inside the bbox. Note that Nominatim default behavior may return results located outside the provided bounding box.

Details

Bounding boxes can be located using different online tools, as Bounding Box Tool.

For a full list of valid amenities see https://wiki.openstreetmap.org/wiki/Key:amenity and osm_amenities.

See https://nominatim.org/release-docs/latest/api/Search/ for additional parameters to be passed to custom_query.

Value

A tibble with the results found by the query.

Examples

# Times Square, NY, USA
bbox <- c(
  -73.9894467311, 40.75573629,
  -73.9830630737, 40.75789245
)

geo_amenity(
  bbox = bbox,
  amenity = "restaurant"
)

# Several amenities
geo_amenity(
  bbox = bbox,
  amenity = c("restaurant", "pub")
)

# Increase limit and use with strict
geo_amenity(
  bbox = bbox,
  amenity = c("restaurant", "pub"),
  limit = 10,
  strict = TRUE
)
