Degree of Urban Dispersion (DIS) 2009 (LEAC Grid), Nov. 2016
The degree of urban dispersion (DIS) characterizes the settlement pattern in a geometric perspective and is based on the distances between any two points within built-up areas (average taken over all possible pairs of points, up to a maximum distance called the horizon of perception). DIS is input to the Weighted Urban Proliferation (WUP) metric, which has three components: the percentage of built-up areas (PBA), the dispersion of the built-up areas (DIS), and land uptake per person (LUP).
The new urban sprawl metric, named "Weighted Urban Proliferation“ (WUP) is based on the following definition of urban sprawl: the more area is built over in a given landscape (amount of built-up area) and the more dispersed this built-up area is in the landscape (spatial configuration), and the higher the uptake of built-up area per inhabitant or job (lower utilisation intensity in the built-up area), the higher the degree of urban sprawl.
The DIS dataset is used in EEA's Urban Sprawl work indicating urbanisation impacts on the land system. It covers EEA39.

The mapping computation steps are:
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 (NUTS0, NUTS2 and 1km LEAC grid were used as the reference layers)
3) DIS values were computed by equations described in https://www.wsl.ch/fileadmin/user_upload/WSL/Services_Produkte/Software_Apps/USM/USM-Toolset-User-Manual.pdf (pages 2 and 17-18 )
4) Newly developed tool called “Urban Sprawl Metric Tool” is available on the https://www.wsl.ch/en/services-and-products/software-websites-and-apps/urban-sprawl-metrics-usm-toolset.html
