landcover {mapme.biodiversity}

Calculate area of different landcover classes

Description

The land cover data shows us how much of the region is covered by forests, rivers, wetlands, barren land, or urban infrastructure thus allowing the observation of land cover dynamics over a period of time. This function allows to efficiently calculate area of different landcover classes for polygons. For each polygon, the area of the classes in hectare(ha) is returned.

Usage

calc_landcover()

Details

The required resources for this indicator are:

• esalandcover

Value

A function that returns tibble with a column for area (in ha) and the percentage covered per landcover class.
