Get sf POLYGON of the national geographic grids from EEA

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.

Examples

# \dontrun{

grid <- esp_get_grid_EEA(type = "main", resolution = 100)
grid_can <- esp_get_grid_EEA(type = "canary", resolution = 100)
esp <- esp_get_country(moveCAN = FALSE)

library(ggplot2)

ggplot(grid) +
  geom_sf() +
  geom_sf(data = grid_can) +
  geom_sf(data = esp, fill = NA) +
  theme_light() +
  labs(title = "EEA Grid for Spain")
