Get sf POLYGON of the national geographic grids from ESDAC

Loads a sf POLYGON with the geographic grids of Spain as provided by the European Soil Data Centre (ESDAC).

Usage

esp_get_grid_ESDAC(
  resolution = 10,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE
)

Source

EEA reference grid.

Arguments

resolution: Resolution of the grid in kms. Could be 1 or 10.
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.
