GISCO Address API

Description

Access the GISCO Address API, that allows to carry out both geocoding and reverse geocoding using a pan-european address database.

Each endpoint available is implemented through a specific function, see Details.

The API supports fuzzy searching (also referred to as approximate string matching) for all parameters of each endpoint.

Usage

gisco_addressapi_search(
  country = NULL,
  province = NULL,
  city = NULL,
  road = NULL,
  housenumber = NULL,
  postcode = NULL,
  verbose = FALSE
)

gisco_addressapi_reverse(x, y, country = NULL, verbose = FALSE)

gisco_addressapi_bbox(
  country = NULL,
  province = NULL,
  city = NULL,
  road = NULL,
  postcode = NULL,
  verbose = FALSE
)

gisco_addressapi_countries(verbose = FALSE)

gisco_addressapi_provinces(country = NULL, city = NULL, verbose = FALSE)

gisco_addressapi_cities(country = NULL, province = NULL, verbose = FALSE)

gisco_addressapi_roads(
  country = NULL,
  province = NULL,
  city = NULL,
  verbose = FALSE
)

gisco_addressapi_housenumbers(
  country = NULL,
  province = NULL,
  city = NULL,
  road = NULL,
  postcode = NULL,
  verbose = FALSE
)

gisco_addressapi_postcodes(
  country = NULL,
  province = NULL,
  city = NULL,
  verbose = FALSE
)

gisco_addressapi_copyright(verbose = FALSE)

Arguments

country

Country code (country = "LU").

province

A province within a country. For a list of provinces within a certain country use the provinces endpoint (gisco_addressapi_provinces(country = "LU")).

city

A city within a province. For a list of cities within a certain province use the cities endpoint (gisco_addressapi_cities(province = "capellen")).

road

A road within a city.

housenumber

The house number or house name within a road or street.

postcode

Can be used in combination with the previous parameters.

verbose

Logical, displays information. Useful for debugging, default is FALSE.

x, y

x and y coordinates (as longitude and latitude) to be converted into a human-readable address.

Details

Brief description of the API endpoints (source GISCO Address API \> Endpoints:

Endpoint Description
⁠/countries⁠ Returns all country codes that are compatible with the address API. Check the coverage map for available countries and see here for a list of official country codes.
⁠/provinces⁠ Returns all provinces within the specified country. Can also be used to get the province of a specified city.
⁠/cities⁠ Returns all cities within a specified province or country.
⁠/roads⁠ Returns all roads or streets within a specified city.
⁠/housenumbers⁠ Returns all house numbers or names within the specified road. It is possible that in certain countries an address may not have a road component. In this case, if a road is not specified then the number of house numbers returned by the API is limited to 1000.
⁠/postcodes⁠ Returns all postcodes within the specified address component (Country or Province or City).
⁠/search⁠ The search endpoint allows structured queries to the address database. Please note that various combinations of each of the parameters can be used in order to retrieve the addresses that share an address component. The API is limited to a maximum of 100 addresses.
⁠/reverse⁠ The API's reverse theme allows you to specify x and y coordinates in order to retrieve a structured address.
⁠/bbox⁠ Returns a WKT bounding box for an address component depending on the parameters specified.
⁠/copyright⁠ Returns the copyright text for each available country in the Address API.

The resulting object may present the following variables:

Property name Description
LD Refers to "Locator Designator" and represents the house number part of the address
TF Refers to "Thoroughfare" and represents the street or road part of the address
L0 Refers to Level 0 of the API administrative levels. Values are country codes consisting of 2 characters.
L1 Refers to Level 1 of the API administrative levels. Values are province names. Please note that "province" is a generic term that may differ between countries.
L2 Refers to Level 2 of the API administrative levels. Values are town or city names. Please note that "city" is a generic term that may differ between countries.
PC Postal Code
N0 Refers to "NUTS 0"
N1 Refers to "NUTS 1"
N2 Refers to "NUTS 2"
N3 Refers to "NUTS 3"
X and Y Refers to the x and y coordinates of the address point
OL Refers to the address' Open Location Code

Value

A data.frame object in most cases, except gisco_addressapi_search(), gisco_addressapi_reverse() and gisco_addressapi_bbox(), that return a sf object.

You can set your cache_dir with gisco_set_cache_dir().

Sometimes cached files may be corrupt. On that case, try re-downloading the data setting update_cache = TRUE.

If you experience any problem on download, try to download the corresponding .geojson file by any other method and save it on your cache_dir. Use the option verbose = TRUE for debugging the API query.

For a complete list of files available check gisco_db.

Set your giscoR cache dir

Description

This function will store your cache_dir path on your local machine and would load it for future sessions. Type Sys.getenv("GISCO_CACHE_DIR") to find your cached path or use gisco_detect_cache_dir().

Alternatively, you can store the cache_dir manually with the following options:

  • Run Sys.setenv(GISCO_CACHE_DIR = "cache_dir"). You would need to run this command on each session (Similar to install = FALSE).

  • Write this line on your .Renviron file: GISCO_CACHE_DIR = "value_for_cache_dir" (same behavior than install = TRUE). This would store your cache_dir permanently. See also usethis::edit_r_environ().

Usage

gisco_set_cache_dir(
  cache_dir,
  overwrite = FALSE,
  install = FALSE,
  verbose = TRUE
)

gisco_detect_cache_dir(...)

Arguments

cache_dir

A path to a cache directory. On missing value the function would store the cached files on a temporary dir (See base::tempdir()).

overwrite
