Get GISCO coastlines sf polygons

Description

Downloads worldwide coastlines

Usage

gisco_get_coastallines(
  year = "2016",
  epsg = "4326",
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  resolution = "20"
)

Arguments

year	Release year. One of "2006", "2010", "2013" or "2016".
epsg	projection of the map: 4-digit EPSG code. One of: "4258": ETRS89 "4326": WGS84 "3035": ETRS89 / ETRS-LAEA "3857": Pseudo-Mercator
cache	A logical whether to do caching. Default is TRUE. 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.
cache_dir	A path to a cache directory. See About caching.
verbose	Logical, displays information. Useful for debugging, default is FALSE.
resolution	Resolution of the geospatial data. One of "60": 1:60million "20": 1:20million "10": 1:10million "03": 1:3million "01": 1:1million

Value

A sf POLYGON object.

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.

Note

Please check the download and usage provisions on gisco_attributions().
