Abstract
The escalating complexities of rapid urbanization necessitate a paradigm shift in urban form evaluation, moving beyond traditional horizontal analyses to incorporate the crucial dimension of vertical growth. This study pioneers a volumetric approach, integrating 3D and 2D spatial analyses, to dissect compactness, sprawl, and their underlying drivers across two contrasting metropolitan regions: the Tehran Metropolitan Region (TMR) and the Greater Sydney Region (GSR) over a 40-year period (1980s–2020s). Our findings reveal a striking dichotomy: TMR exhibits pronounced ‘vertical sprawl,’ characte
