cov_landuse

This function is called by the cov_landuse module and downloads data on the percentage of land used for each category selected. Data is obtained at a 100 m resolution from the Copernicus Global Land Service e.g. https://zenodo.org/records/3939038 as documented here: https://zenodo.org/records/4723921

cov_landuse(shape, year, landuses, async = FALSE)

Arguments

shape

sf. sf object containing the area of interest

year

numeric. The requested year (2015-2019 only)

landuses

vector. List of the requested land use types from the following options: Bare, BuiltUp, Crops, Grass, MossLichen, PermanentWater, SeasonalWater, Shrub, Snow, Tree

async

logical. Whether or not the function is being used asynchronously

Value

a list of containing an item for each land use, either SpatRaster objects when async is FALSE or PackedSpatRaster objects when async is TRUE
