USM toolset - Performance optimized QGIS 4 compatibility
Not QGIS 4 ready Quiet
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
The USM Toolset was developed to facilitate the calculation of Weighted Urban Proliferation (WUP) and all components of urban sprawl for landscapes that include built-up areas (e.g., dispersion (DIS), land uptake per person (LUP)).
About
Weighted Urban Proliferation (WUP) has three components: PBA, DIS, and LUP (or UD). Proportion of built-up areas (PBA) is the ratio of the size of built-up areas to the size of the landscape (reporting unit): PBA = Area of built-up area / Area of reporting unit. Degree of urban dispersion (DIS) measures the dispersion of built-up areas based on the distances between any two points within the built-up areas. DIS is expressed in urban permeation units per square meter of built-up area (UPU/m^2). More dispersed built-up areas have higher DIS values. Land Uptake per person (LUP) is the area of land used per inhabitant or job within the built-up areas, expressed in square meters per inhabitant or job (m^2/(inh. or job)). High LUP values indicate more space used per inhabitant or workplace. LUP is the reciprocal of UD: LUP = 1/UD.
