Calculate biomes statistics (TEOW) based on WWF

Source: R/calc_biome.R
biome.Rd

This function allows to efficiently retrieve the name of the biomes and compute the corresponding area from Terrestrial Ecoregions of the World (TEOW) - World Wildlife Fund (WWF) for polygons. For each polygon, the name and area of the biomes (in hectare) is returned. The required resources for this indicator are:

Format

A tibble with a column for name of the biomes and corresponding area (in ha).

Examples

library(sf)
library(mapme.biodiversity)

temp_loc <- file.path(tempdir(), "mapme.biodiversity")
if (!file.exists(temp_loc)) {
  dir.create(temp_loc)
  resource_dir <- system.file("res", package = "mapme.biodiversity")
  file.copy(resource_dir, temp_loc, recursive = TRUE)
}

  package = "mapme.biodiversity"
