mapSpain (version 0.1.2)

esp_get_gridmap: Get an hexbin or a map of squares of Spain

Description

Loads a hexbin map (sf object) or a map of squares with the boundaries of the provinces or autonomous communities of Spain.

Usage

esp_get_hex_prov(prov = NULL)
esp_get_hex_ccaa(ccaa = NULL)
esp_get_grid_prov(prov = NULL)
esp_get_grid_ccaa(ccaa = NULL)

Arguments

prov

See esp_get_prov

ccaa

See esp_get_ccaa

Value

A POLYGON object.

Details

Hexbin or grid map has an advantage over usual choropleth maps. In choropleths, a large polygon data looks more emphasized just because of its size, what introduces a bias. Here with hexbin, each region is represented equally dismissing the bias.

Results are provided in EPSG:4258, use st_transform to change the projection.
