Hypsometry and bathymetry of Spain from SIANE

Source: R/esp-get-hypsobath.R
esp_get_hypsobath.Rd

Dataset representing the hypsometry and bathymetry of Spain.

  • Hypsometry represents the elevation and depth of features of the Earth's surface relative to mean sea level.

  • Bathymetry is the measurement of the depth of water in oceans, rivers, or lakes.

Usage

esp_get_hypsobath(
  epsg = 4258,
  cache = TRUE,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE,
  resolution = c(3, 6.5),
  spatialtype = c("area", "line")
)

Arguments

epsg

Character string or number. Projection of the map: 4-digit EPSG code. One of:

cache

Logical. Whether to cache downloaded files. Default is TRUE. See Caching strategies section in esp_set_cache_dir().

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 strategies section in esp_set_cache_dir().

verbose

logical. If TRUE displays informational messages.

resolution

Character string or number. Resolution of the geospatial data. One of:

  • "6.5": 1:6.5 million.

  • "3": 1:3 million.

spatialtype

Character string. Spatial type of the output. Use "area" for POLYGON or "line" for LINESTRING.

Value

A sf object.
