Përmbledhja	Urban growth boundary (UGB) analysis uses spatial simulation to design and evaluate containment lines that separate land where urban development is allowed from land to be kept rural. Built on the cellular-automata urban-growth tradition exemplified by Clarke, Hoppen, and Gaydos's self-modifying SLEUTH model, it calibrates how a region urbanizes, then imposes candidate boundaries as hard or soft constraints and simulates land conversion forward in time. By comparing scenarios with and without a boundary, the method estimates how much farmland and open space a UGB would protect, how much it would densify the interior, and whether it would push leapfrog development beyond the line.	Urban sprawl measurement quantifies how compact or sprawling a metropolitan region is by combining several distinct dimensions of urban form into a single composite index. The dominant approach, developed by Reid Ewing, Shima Hamidi and colleagues, captures four factors — development density, land-use mix, activity centering, and street-network connectivity — and folds standardized indicators of each into one score, calibrated so the average region equals 100 and higher values mean greater compactness. Because sprawl is multidimensional, no single variable such as density adequately describes it, which is why the composite-index strategy has become the standard for comparing regions and linking form to outcomes.
