Service Description:

This map contains the raster layers describing urban areas, urban cores, cities, and . Details on the original methodology can be found at links above, the code used to produce the data can be found here - Code to calculate Dartboard, and the raster layers can be downloaded from here - DDH entry for urbanization data

Urban area	label	Definition
Urban areas	ur	contiguous pixels for which the density is above the 95th percentile of the counterfactual
Cores	co	contiguous pixels within urban areas that are above the 95th percentile of the counterfactual within the urban core
Cities	cc	urban areas that have a core
Pop centers	ce	contiguous pixels within a city that are above the 95th percentile of the counterfactual within the city.
