Service Description: The new urban sprawl metric, named „Weighted Urban Proliferation“ (WUP) is based on the following definition of urban sprawl: the more area built over in a given landscape (amount of built-up area) and the more dispersed this built-up area in the landscape (spatial configuration), and the higher the uptake of built-up area per inhabitant or job (lower utilization intensity in the built-up area), the higher the degree of urban sprawl. Weighted Urban Proliferation (WUP) metric has three components: the percentage of built-up areas, the dispersion of the built-up areas, and land uptake per person

Comments: The new urban sprawl metric, named „Weighted Urban Proliferation“ (WUP) is based on the following definition of urban sprawl: the more area built over in a given landscape (amount of built-up area) and the more dispersed this built-up area in the landscape (spatial configuration), and the higher the uptake of built-up area per inhabitant or job (lower utilization intensity in the built-up area), the higher the degree of urban sprawl. Weighted Urban Proliferation (WUP) metric has three components: the percentage of built-up areas, the dispersion of the built-up areas, and land uptake per person
Subject: 1) A built-up areas were selected from the raster High Resolution Layer – Imperviousness Degree (HRL IMD). Only these pixels, where IMD value >= 30% were selected as built-up.
2) The built-up areas layer together with the reference units layer were inputs to the computations (1km LEAC grid were used as the reference layers)
3) Population and employment data at the European level were provided by Eurostat. Utilization statistics (LUP, UD and WUP) at a level of 1km grid were calculated using only population data as jobs data are not available at this level.
4) Differences in spatial coverage of PBA, DIS, UP and LUP, WUP are due to the unavailability of population and job data – mainly in Balkan region and Turkey.
5) Newly developed tool called “Urban Sprawl Metric Tool” is available on the http://www.wsl.ch/info/fokus/zersiedelung/index_EN
