esp_get_grid_BDN: National geographic grids from BDN (Nature Data Bank)

In mapSpain: Administrative Boundaries of Spain

National geographic grids from BDN (Nature Data Bank)

Description

Loads a sf POLYGON object with the geographic grids of Spain as provided by the Banco de Datos de la Naturaleza (Nature Data Bank), under the Ministry of Environment (MITECO).

This dataset provides:

• esp_get_grid_BDN() extracts country-wide regular grids with resolutions of 5x5 or 10x10 kilometers (mainland Spain or Canary Islands).

• esp_get_grid_BDN_ccaa() extracts 1x1 kilometer resolution grids for individual Autonomous Communities.

These grids are useful for biodiversity analysis, environmental monitoring, and spatial statistical applications.

esp_get_grid_BDN_ccaa() provides higher-resolution 1x1 kilometer grids for specific Autonomous Communities, useful for regional analysis with finer spatial detail.

Usage

esp_get_grid_BDN(
  resolution = c(10, 5),
  type = c("main", "canary"),
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE
)

esp_get_grid_BDN_ccaa(
  ccaa,
  update_cache = FALSE,
  cache_dir = NULL,
  verbose = FALSE
)

Arguments

resolution	numeric. Resolution of the grid in kms. Must be one of: 5: 5x5 kilometer cells 10: 10x10 kilometer cells (default)
type	character. The geographic scope of the grid: "main": Mainland Spain (default) "canary": Canary Islands
update_cache	logical. Should the cached file be refreshed? Default is FALSE. When set to TRUE, it will force a new download.
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.
ccaa	character string. A vector of names and/or codes for Autonomous Communities. See Details on esp_get_ccaa() for accepted formats.

Details

The BDN provides standardized geographic grids for Spain that follow the Nature Data Bank's specifications. The data is maintained via a custom CDN and is regularly updated.

Value

A sf object.
