DefineUrban: Defines rural and urban areas based on population density

In SwissTPH/CHWplacement: What the Package Does (One Line, Title Case)

Defines rural and urban areas based on population density

Description

This function defines urban areas as those with a population density higher than rururb_cutoff per pixel. Urban areas are also contiguous and have a minimal total population equal to min_urbsize. The methodology is derived from http://documents.worldbank.org/curated/en/709121516634280180/pdf/122880-V1-WP-P156561-OUO-9-FINAL-ENGLISH.pdf

Usage

DefineUrban(population.raster, rururb_cutoff = 300, min_urbsize = 2000)

Arguments

population.raster	raster map containing population densities
rururb_cutoff	minimal population density to define an urban area
min_urbsize	minimal total population size to define an urban area

Value

a raster similar to population.raster in which all non-urban pixels are masked (i.e. NA)
