Source: R/esp_get_grid_EEA.R
esp_get_grid_EEA.Rd

Loads a sf polygon with the geographic grids of Spain as provided by the European Environment Agency (EEA).

Usage

esp_get_grid_EEA(
  resolution = 100,
  type = "main",
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE
)

Source

EEA reference grid.

Arguments

resolution

Resolution of the grid in kms. Could be 1, 10 or 100.

type

The scope of the grid. It could be mainland Spain ("main") or the Canary Islands ("canary").

update_cache

A logical whether to update cache. Default is FALSE. When set to TRUE it would force a fresh download of the source file.

cache_dir

A path to a cache directory. See About caching.

verbose

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

Value

A sf polygon

About caching

You can set your cache_dir with esp_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.
