agg_worldpop — agg_worldpop • disagapp

This function is called by the agg_worldpop module and downloads data on population density for a single country from worldpop

agg_worldpop(shape, country_code, method, resolution, year, async = FALSE)

Arguments

shape: sf. sf object containing the area of interest
country_code: character. ISO3 code of the country.
method: character. The method used to estimate population. Either Constrained or Unconstrained.
resolution: character. The resolution of the returned raster. Either 100m or 1km.
year: numeric. The year to obtain data for. Either 2000 to 2020 when method = Unconstrained or only 2020 when method = Constrained
async: logical. Whether or not the function is being used asynchronously

Value

a SpatRaster object when async is FALSE or a PackedSpatRaster when async is TRUE.
