esp_get_hydrobasin: River basin districts of Spain from SIANE

In mapSpain: Administrative Boundaries and Static Map Tiles for Spain

River basin districts of Spain from SIANE

Description

River basin districts are the areas of land and sea, made up of one or more neighbouring river basins together with their associated groundwaters and coastal waters.

Usage

esp_get_hydrobasin(
  epsg = 4258,
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  resolution = c(3, 6.5, 10),
  domain = c("land", "landsea")
)

Arguments

epsg	Character string or number. Projection of the map: 4-digit EPSG code. One of: "4258": ETRS89. "4326": WGS84. "3035": ETRS89 / ETRS-LAEA. "3857": Pseudo-Mercator.
cache	Logical. Whether to cache downloaded files. Defaults to TRUE. See Caching.
update_cache	Logical. If TRUE, refreshes the cached file and forces a new download. Defaults to FALSE.
cache_dir	Character string. A path to a cache directory. See Caching.
verbose	A logical value indicating whether to display informational messages.
resolution	Character string or number. Resolution of the geospatial data. One of: "10": 1:10 million. "6.5": 1:6.5 million. "3": 1:3 million.
domain	Character string. Type of river basin district: "land" includes only groundwater areas. "landsea" includes groundwater areas and coastal waters.

Details

Value

A sf object.

Caching

Functions that download data store files in cache_dir. When cache_dir is NULL, they use the active package cache, which defaults to a temporary directory. Set update_cache = TRUE to replace an existing cached file. See Caching strategies in esp_set_cache_dir() to configure a persistent cache.
