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:

Usage

calc_biome()

Value

A function that returns an indicator tibble with variable biome type and corresponding area (in ha) as values.
