gisco_get_airports: Get location of airports and ports from GISCO API

In giscoR: Download Map Data from GISCO API - Eurostat

Get location of airports and ports from GISCO API

Description

Loads a sf object from GISCO API or your local library.

Usage

gisco_get_airports(
  year = "2013",
  country = NULL,
  cache_dir = NULL,
  update_cache = FALSE,
  verbose = FALSE
)

gisco_get_ports(
  year = "2013",
  country = NULL,
  cache_dir = NULL,
  update_cache = FALSE,
  verbose = FALSE
)

Arguments

year	Year of reference. Only year available right now is "2013".
country	Optional. A 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. Mixed types (as c("Italy","ES","FRA")) would not work. See also countrycode::countrycode().
cache_dir	A path to a cache directory. See About caching.
update_cache	A logical whether to update cache. Default is FALSE. When set to TRUE it would force a fresh download of the source .geojson file.
verbose	Logical, displays information. Useful for debugging, default is FALSE.

Details

gisco_get_airports() refer to Europe. All shapefiles provided in EPSG:4326.

gisco_get_ports() adds a new field CNTR_ISO2 to the original data identifying the country of the port. Worldwide information available. The port codes are aligned with UN/LOCODE standard.

Value

A POINT object on EPSG:4326.

About caching

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.
